More likely it's a poor motherboard design around the voltage regulators.  I've
seen numerous instances where Windows works - because motherboard vendors cheat
in ACPI and power hacking via the bios, when Linux (or any other Unix like os)
won't.

Have you upgraded the bios?  Or kept it up-to-date?  Even for Linux, if the chips
and data paths don't get initialized correctly, problems can surface.

FWIW - I've run a GeForce 6600 GT for several now on a diffcult screen - SGI FP1600,
and, while I have had problems with the driver on ocassion - 1600x1080 isn't common nor
VESA, it hasn't let me down.  In fact the only time I've had to drop to 2D is for the 
old Quadro 1 and 2 cards running in some other systems.
