sti(4) can't work until enough of the VM is initialized for it to be
able to allocate memory for the microcode in RAM.

Unlike hp700, hp300 doesn't have any (usable) form of prom console; and
sti(4) was initially written with hp700 in mind, with no provision to
run before uvm is initialized.

Early console on sti(4) on hp300 requires some work in the md console
code selection, as well as in sti(4) itself to pmap_steal_memory() the
memory it needs.

You know where to find that code (-:
