Per my followup posting, the kernel is saying

wdc2:0: before reset, st0=0x80, st1=0x80
atabusattach: ch_drive_flags 0x0 0x0

This is with a kernel from yesterday's 2.0-branch source.  If it will 
help, I can build a -current kernel for that machine, but that will 
take until tomorrow, given how slow my -current machine is.
