This can likely be enabled for more controllers (presumably all the
SFF-based SATA controllers as well as any other PATA that couldn't be on
a physical ISA bus). This is a start though.
Don't some of the VLB controller drivers have their own private 32-bit
PIO implementation? Those should likely be updated to use this support.
