Okay, I've tested 2.6.8 on my Sarge testbed for now. DVI indeed works
with matroxfb enabled, but without Matrox' hallib there's an annoying
flicker. If this cannot be improved with a better kernel configuration
or a later kernel, then I won't use it. See below for the kernel
configuration I've tested.

I do not know if the setup I've tested is entirely correct.

Yeah, I feel pretty much stuck, either. The documentation is not very
great here, I think.

Don't think so.

*sigh* Yes, I've myself tried to figure that out several times, without
success. Well...

'dict dfp' tells me you're right :-)

Hm, I think this works only compiled in. Not sure, though.
(If a module doesn't cut it, then why does the stock Debian kernel
provide one?)

My Kernel 2.6.8 setup with DVI (badly) working:
---- cut here ----
# CONFIG_FB_VGA16 is not set
# CONFIG_FB_VESA is not set
CONFIG_FB_MATROX=y
# CONFIG_FB_MATROX_MILLENIUM is not set
# CONFIG_FB_MATROX_MYSTIQUE is not set
CONFIG_FB_MATROX_G450=y
CONFIG_FB_MATROX_G100=y
# CONFIG_FB_MATROX_I2C is not set
# CONFIG_FB_MATROX_MULTIHEAD is not set
# CONFIG_FB_VIRTUAL is not set
CONFIG_FRAMEBUFFER_CONSOLE=y
---- cut here ----
I hope I've got the relevant options. Kernel commandline:
video=matroxfb:vesa:0x1BB,fv:60
Here 0x1BB is the code for a 1280x1024 resolution.
You will need to tune these for your needs, see
/usr/src/linux/Documentation/fb/matroxfb.txt for your options.
