I don't blame Debian for it (if Xorg dropped support for older hardware,

that's their decision, not Debian's.) But the resolution problem showed

up after I upgraded to 2.6.39 only (no Xorg upgrade involved at that point).

The 2.6.39 kernel I got from Aptosid isn't an RT kernel.

Yup bugs my eyes. My monitor was doing 1280x10124 @ 87HZ before the

kernel upgrade ... When I checked, the Nouveau driver isn't even

installed on the machine. I saw some bug reports for the Nouveau driver

at debian.org saying something about the kernel preventing the driver

from getting EDIT info from the monitor, so the driver assumes a save

1024x768x60hz. Sigh.
I can use video=1280x1024 on the kernel command line to get that

resolution, but it's still using 60hz refresh.
So I set my previous kernel to be GRUBs default and will only select

2.6.39 when I need to.
