My immediate interest is to kill off sounds/oss/ on MIPS because
sound/oss/soundcard.c is fairly ISA centric and does not build for some
some MIPS systems with only half-arsed ISA support, that is no DMA support.

Manuel, I got a DBAu1250 board here and maybe I can find a DBAu1500
Zinfandel board under some dusty hardware pile; would that be suitable for
testing your work?
