I've swapped my nvidia 6600 for a 7600GS, because it has dual-link DVI
output. That broke my framebuffer!

If I boot like this:

Command line: root=/dev/md2 video=nvidiafb:640x480-32@60 atkbd.softrepeat=1

I see this:

nvidiafb: Device ID: 10de0392 
nvidiafb: CRTC0 analog found
nvidiafb: CRTC1 analog not found
nvidiafb: EDID found from BUS1

Mmm, and what you have connected to that dual-link DVI output?  It looks 
like that framebuffer believes that you've connected analog monitor to 
it, which I'm not sure is quite correct given your note that you 
upgraded to get dual link DVI.  You may want to hardcode values for 
FlatPanel & CRTCNumber into NVCommonSetup instead of allowing 
autodetection...

I haven't yet - a plain old CRT monitor is attached currently. I haven't
bought a LCD yet. The messages seem correct. The monitor is attached via
a dvi->vga15 converter, of which I've tried two known working ones.

Thanks,
Jurriaan

So far, I've determined the problem also happens when I boot a 32-bit
system, and it goes partly away when I add the noaccel option.

If I add noaccel, I get a dark grey background, with very dark gray or
black letters on it. It's readable if you can guess what is written,
like boot messages.

xorg works fine (using the nv driver), and the strange part:

once I've switched from Xorg to a console (ctrl-alt-F1), the console
looks fine. Also, if I leave X11 after having switched to a console and
back to Xorg, the console looks fine.

I hope this jogs someone's memory - I basically trying blind. Anyone
care to guess what goes wrong? I didn't think the 7600 was such an
exotic card...

Kind regards,
Jurriaan
