Somebody on 3dfx's linux messageboards asked a very interesting question. I'm sure it's common knowledge, but I couldn't find any specific mention.
 
How far along is 3dfx/PPC? I know I saw some mention of ATI/PPC, but as I'ma  3dfx/Nvidia man in the X86 world, I'm afraid I didn't pay enough attention. Is 3dfx/PPC currently working/expected to be working any time soon?
