Console font is overwritten by a vram buffers allocation (seen when switching from X).
Last modified: 2008-06-29 11:30:52 UTC
After X, the console has all the characters except for a few replaced with pseudographics.

nouveau: allocate drm-use vram buffers from end of vram.
This avoids seeing garbage from engine setup etc before X gets around
to pointing the CRTCs at a new scanout buffer. Not actually a noticable
problem before G80 as PRAMIN is forced to the end of VRAM by the hardware

Save and restore the framebuffer offset.
This is a blind guess, let me know if it works out ;-)

This was missing in the /var/log/dmesg:
