The same on debian/testing. After a dist-upgrade, which made the transition
from XFree86 to X.org CTRL-ALT-Fx does nothing.
Linux kernel is 2.6.15 on x86, Debian X server version is 6.9.0.dfsg.1-4, which
is 6.9.0 final according to the Debian changelog.
xorg.confs InputDevice Section is:
Section "InputDevice"
        Identifier      "Generic Keyboard"
        Driver          "keyboard"
        Option          "CoreKeyboard"
        Option          "XkbRules"      "xorg"
        Option          "XkbModel"      "pc105"
        Option          "XkbLayout"     "en"
        Option          "XkbVariant"    "nodeadkeys"
EndSection
Can provide additional info, if needed: sbi_@gmx.net.

stefan, your problem is occurring because 'en' is not a valid layout name.  do
you mean 'us'?  (even so, 'nodeadkeys' is not a valid variant of us.  which
layout do you want, exactly?)

ferris, the gentoo bz is down.  could you please attach your log and the
keyboard section of your xorg.conf here?

Confirmed, after fixing that it works.

Sure.  With that change, kernel-2.6.x is fine; kbd section is:
===============================
Section "InputDevice"
  Identifier  "Keyboard0"
  Driver      "kbd"
  Option      "XkbModel"    "type5"
  Option      "XkbRules"    "xorg"
   Option      "XkbLayout"   "us
EndSection
=======================
kernel-2.4.x remains broken; here is one Keyboard section from 2.4:
=======================
Section "InputDevice"
  Identifier  "Keyboard0"
  Driver      "kbd"
  Option      "Protocol"    "Standard"
  Option      "XkbKeycodes" "sun(type5)"
  Option      "XkbModel"    "type5"
  Option      "XkbRules"    "sun"
  Option      "XkbLayout"   "us"
  Option      "XkbTypes"    "types/complete"
  Option      "XkbCompat"   "compat/complete"
  Option      "XkbGeometry" "sun(type5unix)"
   Option      "XkbSymbols"  "sun/us(sun5)"
EndSection
==============================
And here's what the log file says about the keyboard for kernel-2.4.x
===============================

(**) Option "CoreKeyboard"
(**) Keyboard0: Core Keyboard
(**) Option "Protocol" "Standard"
(**) Keyboard0: Protocol: Standard
(**) Option "AutoRepeat" "500 30"
(**) Option "XkbRules" "sun"
(**) Keyboard0: XkbRules: "sun"
(**) Option "XkbModel" "type5"
(**) Keyboard0: XkbModel: "type5"
(**) Option "XkbLayout" "us"
(**) Keyboard0: XkbLayout: "us"
(**) Option "XkbKeycodes" "sun(type5)"
(**) Keyboard0: XkbKeycodes: "sun(type5)"
(**) Option "XkbTypes" "types/complete"
(**) Keyboard0: XkbTypes: "types/complete"
(**) Option "XkbCompat" "compat/complete"
(**) Keyboard0: XkbCompat: "compat/complete"
(**) Option "XkbSymbols" "sun/us(sun5)"
(**) Keyboard0: XkbSymbols: "sun/us(sun5)"
(**) Option "XkbGeometry" "sun(type5unix)"
(**) Keyboard0: XkbGeometry: "sun(type5unix)"
(**) Option "CustomKeycodes" "off"
(**) Keyboard0: CustomKeycodes disabled
===========================================

Note that with kernel-2.4.x, the Compose key works fine, but AltGraph does not
do anything (using this Keyboard section).

uh, you can't combine kccgst (keycodes/compat/geometry/symbols/types) and rmlvo
(rules/model/layout/variant/options).  i suggest just trying with
rules/model/layout.

ferris, what change did you make? did you also have a layout of 'en'?

I had 'en_US' (which long ago was required).  I changed to 'us'.  Using just
rules/model/layout makes no difference whatsoever with kernel-2.4.x (Note that
with xorg-6.8.2 and the deprecated kbd driver, what I have works fine. With the
fix to the kbd driver, 6.8.2 and 7.0 behave the same under kernel 2.4.x.)

yeah, en_US isn't valid anymore.  as for the fix to the kbd driver you mention,
I have no idea which, but okay ...
