here is the entry:
ctlr
	0xC0060=" Diamond Computer Systems" 
	link=vga
	hwgc=s3hwgc
	ramdac=att20c490
	link=s3clock
	clock=icd2061a
	ctlr=s3805
	link=ibm8514
I hacked this entry together by looking at other entries and by doing some 
guessing. As I said before, the ramdac is actually Diamond's SS2410, but
it is (somewhat) compatible with the att20c490.  

when I start aux/vga it recognizes the card (i.e., it finds that string in RAM
but the display is funky.  I get what looks like a split screen, and the top 
half and bottom half are the same, with some other wierd stuff.  It's hard to 
describe, but in my experience these symptoms are evidence of a timing problem.

I've read the the order in entry is the order in which the init functions are
called.  Maybe I should try reording them ?

thanks,
