The problem is that the aha1742 does not correctly emulate 1542 intructions
3 and 4 (used in the 'as' driver)

that's all ok

	a SNAFU with naming  and partitions.

No, the aha1742 is FULLY SUPPORTED.

the new disks are using the NEW scsi drivers.
the devices are called sd0[abcdefgh]
rather than as0[abcdefgh], though as0 and sd0 are the same device
(same major/minor numbers)
if you can use "disklabel -r -w sd0 <disktab-entry> <label> <sdboot> <bootsd>"
you may have more success.
