When trying to launch X with KMS enabled on a R300 I get a kernel crash. The same software versions works fine on another computer with KMS and RV770.

This laptop doesn't have it's flat panel attached. The only monitor is a lcd connected through the vga connector.
Looks like it misdetects the LVDS panel size as 0x0 and then crashes as a consequence of that.

The DDX has code to skip panels that are 0x0. Needs to be ported to kms.

Can you try again with drm-next? Should be fixed in: http://git.kernel.org/?p=linux/kernel/git/airlied/drm-2.6.git;a=commitdiff;h=2ffb842948ba64b03986f4064140a74c1780c44b
Works perfectly. Thanks.
