Default openGL hard freezes computer

I have an nVidia Corporation NV25 [GeForce4 Ti4200] (rev 163) installed in my machine on an Intel 845G motherboard (Intel Corp. 82845G/GL [Brookdale-G] Chipset Host Bridge). My machine is running debian unstable with the binary nvidia 4496 version drivers on a 2.4.21 kernel. The AGP driver being used is the NVIDIA one, with an AGP rate of 4x. The nvidia card is sharing IRQ9 with the usb-uhci hub.

My problem is that OpenGL applications (WineX running GTA, and OpenGL screensavers) seem to be hard freezing my machine and somehow corrupting the video ram. When a GL application has been running, often (but not always) the screen will freeze and become sort of a psychadelic rainbow colored static (like TV with no signal, but with pinkish purplish bluish tones instead of black and white ). I then have to hard power off my machine (have to hold the power button for >4 seconds, as it doesn't respond immediately), as I can't even ssh to it. If i just hit the reset button, the video ram is still corrupted, but it does try to boot.

has anyone else seen anything like this? any recommendations on how to fix it?
