Hiho! :-)

Thanks a lot for working on this!

As soon as X is started, things work fine. Before that (as soon as vt
is initialized after the boot menu), output on all ttys is flickering,
resolution is at 640x480 (guessing here) and changing anything via
vidcontrol fails with "inappropriate ioctl for device". Also, screen
output starts overlapping, but a "clear" command fixes that
temporarily. The "Alt-Gr" key does nothing, manually entering ascii
keycodes via alt+number (e.g. alt-124 for |) works.

Relevant pciconf output:

vgapci0_at_pci0:0:2:0:     class=0x030000 card=0x40011297 chip=0x2e328086
rev=0x03 hdr=0x00 vendor     = 'Intel Corporation'
    device     = '4 Series Chipset Integrated Graphics Controller'
    class      = display
    subclass   = VGA

vgapci1_at_pci0:0:2:1:     class=0x038000 card=0x40011297 chip=0x2e338086
rev=0x03 hdr=0x00 vendor     = 'Intel Corporation'
    device     = '4 Series Chipset Integrated Graphics Controller'
    class      = display

Best regards,
Marc
