Go 7600: 640x480 & 640x512 do not work
this has been happening for ages, but I was noy determined enough to post a bug report. Anyway, when I select 640x480 as a screen resolution, the picture will be wrong: in stretched some parts of the image will get missing, and with centered/aspect ratio scaled the picture will be completely busted (looks like some scanline effect).
Out of resolutions listed in the nvidia-settings, this happens only with 640x480 and 640x512, others work fine. Bug report log attached. This is currently on Fedora 13 x86_64 and Toshiba Satellite A100-847 laptop.
