MFC important fixes by sos@:
Implement a workaround of the datacorruption problem on ServerWorks
HT1000 chipsets. The HT1000 DMA engine seems to not always like 64K
transfers and sometimes barfs data all over memory leading to instant
chrash and burn.
Also fix 48bit adressing issues, apparently newer chips needs 16bit
writes and not the usual fifo thing.
