John Baldwin 31a51bf683 Trash the PnPBIOStable pointer later on when we know that the acpi probe
and attach routines have succeeded so that if they fail we can still use
the PnP BIOS to find ISA on-board devices.  The fact that we do this here
is gross but fixing it properly involves a lot more work.
