Comment(by tonestone57):
I decided to quickly test my Atom 330 with i945G (older) graphics but with
Debian. It listed additional modes from the Ironlake (Core i3 - newer)
graphics. Leading me to believe something is really wrong - maybe Intel
video BIOS issue? I will have to wait for newer Linux distros and test
out Intel Ironlake again in the future. ie: older Intel graphics chips
should not have more and higher resolution VESA video modes than newer
Intel graphics card. Highest VESA resolution available for Ironlake is
1024x768.
i945G output from hwinfo in Debian:

I also should check in Haiku with i945G to see if I get access to these
modes or not.
