fbset problem or how to change the res?

[Ron Farrer <rbf@yaveng.farrer.net>]

I'm trying to change the screen res to 1024 x 768 @ 32 or 24 bpp. The
problem is that no matter what I try, I end up with a blank screen and
the only option is to blindly type and reboot... Here is what I'm doing
(perhaps I'm doing it wrong?):
fbset -g 1024 768 1024 768 24

The reason I want to change the res is because everthing is HUGE in
XF86-4 at the default 800 x 600. I have a voodoo 3000 PCI as the fb dev.

TIA,
Ron
