Okay, so about half a year back I was installing RH 5.1, and had a little
trouble using Xconfigurator to create my XF86config file. I came here to
TLUG, and Chris told me to make the following adjustments:

	(--) SVGA: PCI: Trident TGUI 96xx rev 211, Memory @ 0xfb800000, MMIO
@example.com
	(**) SVGA: chipset:  generic
	This is your problem.
	Remove the "chipset generic" line from your XF86Config

Cool. Then Matt recomended i use xf86config to configure my video card.
Armed with these gems of knowledge, I went to m machine and had it running
smoothly in no time.
So here it is six months later, and I'm setting up RH 5.2, and i runn into
the same problem again. "Aha!" Thinks I, "I'll just go to the TLUG archive,
get the same solution as before, and everything will be peachy".
So i go home and use xf86config to set up my XF86config file, and then I
remove the "chipset: generice" line. And my monitor goes haywire when I say
"startX". 
So after fiddling around, I discover that this time Xconfigurator has the
highest rate of success, because it won't give me a resolution higher than
320X200, but at least it doesn't turn my monitor into blithering idiot
(that's my job!)
Sigh.
So what can i try here?
_________
Included here is my XF86config file. I'm pretty sure the problem lies in
the Screen section, where, in the SVGA part, all the lines for my card have
been commented out. However, I tried uncommenting them and commenting out
mention of a "generic" video card, but that gave me near random results.
