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.
