I'd be interested to know if the higher resolution modes work at all for you. I tried a 0x0181 card recently and just could not get it to do anything >= 1280x1024. I made the clock frequency change, but that wasn't enough. It was as though the "I am a mode < 1280 pixels wide" bit (0x04 in CRT 0x1A) was set, even though it was very clearly not set: I could run in 1268x1024 just fine, but pushing it up to 1280 broke things. Modes like 1600x1200 just gave completely blank screens. I traced through the VGA BIOS initializing the card and still couldn't figure out what was going on in the 1280x1024 case. The BIOS did not give 1600x1200 as a mode option, though 1400x1050 was (and didn't shed any light on the subject). This was all in digital mode. Finally I rewrote the driver to be almost exactly like the XFree86 driver (even closer than the current one) and then nothing worked, presumably because of some bugs I introduced but didn't track down. At this point a week had gone by, and I gave up, threw out all the code I'd changed, and just used VMware. So much for Nvidia's great backwards compatibility. Sigh.
