Stupid user tricks dual Radeon 7500 cards

["K. S. Griffiths" <kgriffi siue edu>]

I'm not nearly as experienced with Linux as I'd like to be, try as I 
might on my own I can't get dual head to work on my system.

Specs are PIII 733, Tyan Motherboard, one ATI Radeon 7500 in AGP slot, 
second ATI Radeon 7500 in PCI slot.  I have one 15" LCD that supports 
1024x768 that I want to be my secondary monitor, and a 17" LCD that 
supports 1280x1024 that I want to use as my primary.  Individual 
desktops are preferred as I need the 1280x1024 resolution.  The 17" LCD 
is physically below the 15" LCD.

The setup works under SuSE Linux just fine but SuSE was being a PITA 
about some of the apps I need to use for my job.  Below is my XF86Config 
with most comments edited out:
