  I know it doesn't help you directly, but I have been working on ATI TV out 
support off-and-on for a few months.  I have a laptop with an ATI Rage 
Mobility M (Mach64 based) chipset.  I think Rage128 does things similarily.  
Anyhow, I am able to write the interrupt calls to set TV out mode, but this 
is rather useless on Linux.  So I used an emulator program and was able to 
get a trace of the port accesses which are done when the bios call is done.  
It's very long but I think I have most of it deciphered.  I'm now able to 
write a linux program which enables the TV out port on Mach64 but I don't 
have the timing loop worked out.  This means it doesn't sync.  If anyone 
wants to take up this work, I can try to get it all together for you (or 
perhaps it's in the GATOS CVS already.... I was told it would be added at 
some point).
