Well, it's only a problem for full duplex :) If you are write-only in
poll(), read doesn't apply. Read-only in poll(), and you start DMA.
For full duplex... my Via driver starts DMA'ing. That was my
interpretation of the spec.

What was the complaint?
FWIW I highly recommend Rui Sousa's oss-test stuff. Check out the
"emu10k1" module from Creative's CVS server, and look in the
emu10k1/utils/oss-test directory.
