Sorry, I have forgotten about this.

I don't have better idea. For ATA translation seems indeed more
platform- then controller-specific. May be I would just preferred to see
this hack to be done inside XPT_CALC_GEOMETRY handler, as it is done now
for PC98 SCSI. But looking that whole this topic is quite crappy and
hopefully going to die sometimes, I won't argue much against committing
this as-is for now.
