If you bend the definition of "hardware accelerated" enough, SIMD
extensions like MMX/SSE... would qualify. :)

The DSP on emu10k1 cards is the only one supported in Linux.

I don't know how similar that DSP is to the one on Creative's game
("consumer") cards, but it probably is somewhat related. But Creative
doesn't release documentation, so we can forget it.
