    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
    CONFIG_FB_MATROX=y
    CONFIG_FB_MATROX_G450=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
