Umm, on -current iee(4) even without my patch gets
timeouts and errors on heavy load:
iee0: iee_watchdog: transmit timeout 22
iee0: iee_intr: receive error 1, rfd_status=0x0000, rfd_count=0x0000

Could newer pmap require more strict bus_dmamap_sync(9) calls
in MI drivers?  IIRC hppa doesn't have BUS_DMA_COHERENT support.
(I don't know if it will work on other newer machines like 712)

I'll commit MI i82596 changes anyway, but should we still disable
iee(4) on its hp700 attachment, and enable it only in netbsd-5 branch?
(though ie(4) also gets timeouts even on netbsd-5...)
