Awesome - I love to see NetBSD on new^Wold-but-different hardware :-p

In terms of having it show as an HP332 I assume the easy bit would be
adding HP_332 to sys/arch/hp300/include/hp300spu.h and then looking
for all the cases of HP_340 in sys/arch/hp300 and adding an HP_332 as
required. The hard part would be working out how to tell them apart
and updating the assembly in hp300/locore.s stand/common/srt0.S :)

Presumably HP-UX could tell them apart so presumably there must be
some way to probe it...
