	OK updated and tried nata on my A8V based box with two opticals and
a SATA hard disk - I got a boot time trap (output and trace with arguments
elided below - if the trace arguments would help I can probably do it again
and type them up):

kbd0 at atkbd0
kernel trap 12 with interrupts disabled

	Finally from a boot with the ata kernel:
