I've had identical problems.  I've got an SP3G (Saturn II, Rev 4, Award BIOS)
and a clone taiwanese VL BUS (Opti chipset, non-GUI AMI BIOS) that both
fail to reboot with 1.0 and 1.0A.

OS/2 is able to reboot the Opti chipset board but not the SP3G.  DOS does

In BSD/OS (BSDI) 2.0 they've added code to support the kernel making BIOS
calls.  It seems that sort of thing would be useful in a few places (reliable
reboots, the kernel being able to query the BIOS after going to protected
mode - helpful for machines with non-std CMOS layouts to query memory and
similar things, getting the translated geometry accurately from the BIOS for
those BIOS that aren't good about writing that info to disk (like Adaptec)
