Log:
Add support for tagged queuing on ATA drives. There is only support for
IBM's DPTA and DTLA series of drives (no other disk vendors are known
to support this) on non-Promise controllers (promise controllers lockup
when given the tagged queuing specific commands).
It gives especially master/slave comboes about 5% better performance.
Add support for the Promise ATA100 OEM chip (pdc20265)
Add support for the Cyrix 5530
Change the way status is read from the drives, use the alternate
status reg when possible.
Better support for DEVFS, the acdXtY devices are now created when needed.
Lots of little cleanups.
