A couple of comments:

Does it have an HIL connector on the back?  (the HIL is the HP-style
keyboard/mouse/etc. interface)  If the machine doesn't have an HIL at all
I'm not sure the kernel will boot.

Does it have ethernet (802.3) or does it have token-ring?  None of the
BSDs support the Apollo token ring.  You could be stuck without a LAN.

As I recall, you will have to reconfigure the boot ROM somehow to get an
HP-UX style boot sequence.  Unfortunately, I don't remember how to do this.
If it is in "HP-UX mode" you should see something like:

The graphics card should be OK, though you might pull it just to be safe
(and ensure that the console output comes out on the serial port).
