Manually setting a single mode is probably the easiest:

Section "Screen"
 	Identifier "Screen0"
 	Device     "Card0"
 	Monitor    "Monitor0"
 	DefaultDepth 24
 	SubSection "Display"
 		Viewport   0 0
 		Depth     24
 		Modes "1280x1024"
 	EndSubSection
EndSection

That might be enough, or you might have to go to 1024x768.  You could 
limit the entries in the Monitor section to trick the card into picking 
a single reasonable mode, like VertRefresh 70, or HorizSync 30-50. 
(Assuming this is a CRT.  If it's an LCD, use VertRefresh 60.)

Incidentally, Radeon 7000 cards are available in standard PCI for $20 or 
so.  Not a great card, but quite an upgrade over a Mach64, and supported 
by a current driver.
