This page has good information on custom video modes for the SGI O2: http://dart.ncsa.uiuc.edu/slevy/o2-stereo/.

The author of that page has a zip file with useful files and information: o2-stereo.tar.gz.

I wrote a couple video modes of my own:

1400x1050 @ 60 Hz
1400x1050_60.info
1400x1050_60.vfo
1400x1050_60.vfs
1600x1024 @ 60 Hz
1600x1024_60.info
1600x1024_60.vfo
1600x1024_60.vfs
1600x1024_60.vfs.old
I also have a script to help me remember how to compile new modes:
mkvfo
