bad4ce7d91 - Use the correct devclass name ("acpi" vs "ACPI") to detect if acpi0 is 
present and thus that the PnPBIOS probe should be skipped instead of
  having ACPI zero out the PnPBIOStable pointer.
- Make the PnPBIOStable pointer static to i386/i386/bios.c now that that is
  the only place it is used.

092a5c4530 Remove atdevbase and replace it's remaining uses with direct references to 
KERNBASE instead.

79005bbdbe Add new bios_string() which will hunt for a string inside a given range 
of the BIOS.  This can be used for finding arbitrary magic in the BIOS
in order to recognize particular platforms.

bdaeb9cc90 Fix the argument specifier for the PnP BIOS function 2 
(PNP_SET_DEVNODE). The second argument is not a segment:offset
pointer, but a 16 bit short.

0b9427de88 The general conesnsus on irc was that pci bios for config registers 
and such was just a bad idea and one that users should be forced to
enable if they want it.  This patch introduces a hw.pci.enable_pcibios
tunable for those people.  This does not impact the pcibios interrupt
routing at all.

96f5284585 More updates to the ACPI code: 
- Move all register I/O into acpi_io.c
 - Move event handling into acpi_event.c
 - Reorganise headers into acpivar/acpireg/acpiio
 - Move find-RSDT and find-ACPI-owned-memory into acpi_machdep
 - Allocate all resources (except those detailed only by AML)
   as real resources.  Add infrastructure that will make adding
   resource support to AML code easy.
 - Remove all ACPI #ifdefs in non-ACPI code
 - Removed unnecessary includes
 - Minor style and commenting fixes

300451c472 Some more i386-only BIOS-friendliness: 
- Add support for using the PCI BIOS functions for configuration space
   accesses, and make this the default.

 - Make PNPBIOS the default (obsoletes the PNPBIOS config option).

 - Add two new boot-time tunables to disable each of the above.

and always reload the selectors for every bios call.

dc055b0c58 Remove the SMBIOS detection and definitions; this should be handled in a 
loadable module (under development).

cb5f885bdf Search for and interrogate the PnP BIOS if found. This code just prints 
the PnP device IDs in verbose mode; it does not (yet) save any resource
data or contribute to the PnP process nor resource management.

496027bf08 Major update to the kernel's BIOS-calling ability. 
- Add support for calling 32-bit code in other segments
 - Add support for calling 16-bit protected mode code

Update APM to use this facility.
