I found that in i4b_ifpi2_pci.c, in avma1pp2_disable
there is a "/* could be wrong*/" before writing
0x07 into STAT0_OFFSET. I peeked at Linux driver
and it looks like that it writes 0x0 when device is disabled.
So, I went and changed the source like this:

*** /tmp/orig Fri May 10 11:31:30 2002
--- i4b_ifpi2_pci.c Fri May 10 11:31:41 2002
***************
*** 950,957 ****
bus_space_handle_t bhandle =
rman_get_bushandle(sc->sc_resources.io_base[0]);
bus_space_tag_t btag = rman_get_bustag(sc->sc_resources.io_base[0]);
! /* could be wrong */
! bus_space_write_1(btag, bhandle, STAT0_OFFSET, 0x07);
}
static void

bus_space_tag_t btag = rman_get_bustag(sc->sc_resources.io_base[0]);
! /* could still be wrong */
! bus_space_write_1(btag, bhandle, STAT0_OFFSET, 0x00);

Tadaaa! I was able to reboot the machine without cycling the power.
Maybe someone with card specs could verify if this change is correct ?
