Unable to use 1280x1024 in OpenGL games on FreeBSD (NVRM output included)

[Aphax]

It seems that I can't select 1280x1024 resolution in OpenGL games (it works fine in 2D), 1024x768 seems to work, but since my screen's native res is 1280x1024 I'd really like to use that one. With 1280x1024 most games seem to just crash and I get the following output on my console:

NVRM: Xid: 25, L1 -> L0

Can anyone help me figure out what's wrong?

PS: Sorry about not including the requested .log file, it seems the nvidia-drver in the FreeBSD ports tree doesn't come with the bug report shell script, I will look for it however and attach it if I can find it.

Sorry for the shameless bump, does anyone have any idea? I want to add that the problem doesn't appear in all games under FreeBSD. I seem to be able to use 1280x1024 with the games/quake2lnx (which despite the 'lnx' is built under FreeBSD natively) port. Come to think of it, it seems it's only the Linux games that have the problem.

Also, the NVRM errors pasted above I suspect are printed *after* I hit CTRL+ALT+F1 to kill off the frozen game. The reason I say this is that the first time I went to ttyv0 to escape out of the game there were only 4-6 lines or so, when I did it again there were more.
