Status Report:

The initr300 program itself locks up my Radeon 9600 (Saphire with 256MB 
memory). lspci -v says

Mobility 9600] (prog-if 00 [VGA])

I used 

#define ADDR 0xfbe00000

The locksup happens immediately after the 'S 02' is flashed up on the 
screen... When the lockup happens my DVI-I monitor reports it's going to 
sleep because of no signal. My analog monitor on the same card just sits 
there...

Plus I get lots of RD errors from the first part...

FWIW my card locks up when trying to load DRI as well (recent thread on the 
list).
