FWIW, I'm shaking down a 8.5*100 T'bird VIA VT8363 (no "A") 
Northbridge & VT82C686A (Southbridge).  KT133 no A.  No HPT366.

I had terrible read errors on a single UDMA66 HD: one in 5 md5sums 
on an unmounted 1.5 GB partition was different.   WD Diags said 
drives were good (sectors verified OK). Swapped PS, RAM, HDs, 
cables, PCI cards, 2.2/2.4/FreeBSD kernels, nothing helped ...  

...  until I slowed the SDRAM down from the PC133 (it really _is_
and passes memtest-86 and my burnMMX)  down to PC100.  At least 
UDMA is still working, even if my RAM is decidedly slower. YMMV

I've now tested 9 hrs copying a 500 MB file back and forth on the
same drive without error.  21 hrs copying back and forth  and 
md5sum'ing from /dev/hdc3 [UDMA66] is OK too.
