The BlitPixie routines contain a lot of optimized code, including some AltiVec...
Maybe some of it can be put to good use in the altivectorize project, perhaps ?

Wish they packaged the download in something other than StuffIt, it hurts to have to CVS everything Maybe some of it can be put to good use in the altivectorize project, perhaps ?

This might be interesting for integrating ideas into such things as the VESA or VGA framebuffers or X drivers. AltiVec code here would make a lot of difference (4+ pixels at once etc.) to performance on "unsupported" cards.
I wonder also how much acceleration the Linux framebuffer device wants to support but more importantly does the Linux kernel REALLY support AltiVec/VRSAVE and so on when it switches tasks? You can't even use the FPU under most circumstances and framebuffer drivers are generally kernel compiled, not modules or userspace..
