Hi, Richard!

Yeah, Marek kicks ass, he's one of the original developers of r300g. :)

My Xpress 200M laptop has a Turion X2 TL-60 with 4 GiB of RAM, so I'll just
shut up. :P

I build my own kernels straight from Linus' git, but that's trivial.
I've never built Mesa, but I might as well just bite the bullet. ;) Something
tells my I'll be needing it soon, when I try to get a X1950 XT running on my
Power Mac G5. I have no idea about the current state of r300g on big-endian,
it's most likely bitrotted (I'd love to be wrong, though).

Speaking of which (and totally off-topic), how hard and/or beneficial would it
be to also implement shader caching on r300g?

Great! I often lurk around Phoronix too. I don't think I'll need extra help
after RTFM, but I appreciate it. Thanks a lot, Richard! :)
