There is a regression here: I boot my kernel like this:
kernel /boot/vmlinuz-2563matrox root=/dev/hda7 video=matrox:vesa:0x11E,fv:80,sgram hdc=scsi apm=smp apm=power-off nosmp=1
and have the following .config:
CONFIG_VT=y
CONFIG_VT_CONSOLE=y

I see a continuous strip of alternating blocks, of sub-character size,
at the extreme right end of my screen. The colors seem linked to the
color of the line with the cursor in some way.
After leaving XFRee, a piece of chbg's background picture is shown for a
short while, then the blocks return.
Kind regards,
Jurriaan
