One thing: I'd be interested in figuring out what happens if you simply leave this nasty ATI BAR unassigned (write 0xffffffff and then 0 to it). Will the controller fail ?
Well, according to Matt Porter, 0 is a valid address in PCI 2.2. So how do you
disable BARs for PCI 2.2-compliant devices?
And I'm afraid what XFree86 4.x will do with BARs set to 0. Probably it will
try to relocate them. I guess that's how it crashes on my box with an
unitialized S3...

when I'm talking to journalists I just say "programmer" or something like that.
