Comment (by axeld):
I am not sure if the nvidia driver is using create_display_mode() at all.
Older drivers tend to implement this bit on their own with their own mode
list. That would be the first thing to test.
As you can see in your syslog, the nvidia VESA mode does not contain
anything above 800x600, and therefore, you won't find it when using VESA.
That looks like a pretty poor BIOS implementation, or maybe the EDID
information from your monitor are just broken (more likely).
The driver should not ignore the EDID information per se (ie. I wouldn't
want to see your solution in trunk), but should either try harder to
detect broken EDIDs (preferred), and/or have a setting that achieves this.
