I experienced the same issues regarding to the resolution and the 60 Hz

stroboscope (and a non working mouse wheel for my PS/2 mouse, slow down

Internet for PPPoE etc.) with current debianoid Linux. They drop old

hardware, even if they claim not to do.
Regarding to the monitor, I downgraded X and then I got back the wanted

1152x864@90Hz. The monitor can do better than 90 Hz, debianoid Linux for

my setup can't anymore, but I guess there's no difference between 90 Hz

and > 90 Hz.
I'm using xserver-xorg-video-nv 1:2.1.17-3 + depending X packages, it's

from Debian stable, while anything else should be from Debian testing.

For Debian testing there's no nv driver anymore and the nouveau doesn't

work on my machine, when using a kernel-rt.
Perhaps a downgrade will solve the issue on your machine too. 60 Hz

vertically is unhealthy.
