 Finally I've found there is a dumb problem, i.e. the rom address
 taken from PAGE0->pd_resv2[1] (0xf0080000) just works:

 - OpenBSD/hppa doesn't check sti_sgc_opt[] values against
   ca->ca_type.iodc_revision for on-board (primary) sti(4)
 - sti_sgc_opt[] is different from OpenBSD (not sure why)
 - no info where STI_GOPT[1234567]_REV macros came from
