A bit off topic, but does ISA DMA work on these ports?
Last time I tried AHA-1542 and PCnet-ISA on cats,
both of them didn't work at all.

Current _isa_bus_dmamap_load() in footbridge/isa/isadma_machdep.c
returns physical address for ds_addr, but is it really OK for 24bit
ISA bus? And does cats really require bounce-buffer for isadma?

Furthermore, _isa_bus_dmamap_sync() does not handle cache coherency
at all, but it should do like arm/arm32/bus_dma.c.
