My expiriences with ahc cards on alpha were ugly.
I don't know what to expect from non ahc based adaptec cards.

No.

Otherwise a busdma driver is required only for large memory situations,
which we curently don't support yet.

My impression was that Miatas are also limited to 1G by hardware?
Does anyone know if Miatas can be fit with >1G?
