The card has NVRAM, but the "bios" doesn't do anything on MacPPC, unless
NetBSD uses the Open Firmware.  (I've read elsewhere that people have had
trouble with that)

The NVRAM on the card is used by the Adaptec drivers under MacOS and windows,
and can be examined from the MacOS side with a utility called "Power Domain
Control", which can be downloaded from Adaptec's web site.  However,
unless the NetBSD ahc driver *uses* the NVRAM - i.e. uses the values
stored there in the same way as the Adaptec drivers, I would be
cautious about making statements about the NVRAM's effects on
operations of the card.
