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
CONFIG_HW_CONSOLE=y
CONFIG_AGP=y
CONFIG_AGP_VIA=y
CONFIG_DRM=y
CONFIG_DRM_MGA=y
CONFIG_RAW_DRIVER=y
CONFIG_VGA_CONSOLE=y
CONFIG_VIDEO_SELECT=y
CONFIG_DUMMY_CONSOLE=y
CONFIG_FRAMEBUFFER_CONSOLE=y
CONFIG_PCI_CONSOLE=y
CONFIG_FBCON_ADVANCED=y
CONFIG_FONT_SUN12x22=y
CONFIG_FONTS=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
