I've run two systems with PCM right since the first newbus commit, and it's
worked for me. Admittedly I don't use it all that often, but it's never
paniced and I don't recall getting any more sound problems than usual.
I checked that the isa_dma.c code is an exact split of the dma code that
used to be in the old isa.c, there are zero changes to the isa dma code.
