ACPI, SMM, and PIIX fixes, fixes quite a few boards, also fixed the Via Apollo series northbridge ID's, some CPU instructions on both 808x and 286+, and added SMM to 486's (Intel and AMD), WinChip and WinChip 2, and VIA Cyrix III, also removed the TC430HX and the Toshiba machine from the Dev branch.
