Through the PITA of endiannness, clock has to be MHz freq << 8.
Don't trust NVRAM on SBus cards.
Set a default initiator ID sensibly.
SBus/ISP now working, what with the change to sbus.c earlier today.
flags include INTR_MPSAFE. Put the flags in a common place so that

This code does not imply that SBus cards work yet. They hang for me.
But I can't netboot the latest snapshot on my ultra1e, and things
hang at bus_setup_intr time.
Since I'm offline for a while, I thought I'd toss this in in case somebody

and wait until I get back to check things in.
