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?
