UMC HB4 shadow RAM overhaul and SMRAM fixes, slight changes to SiS 85c4xx, a fix for SiS 85c50x, fixed SMBASE on 486 (it should *NOT* zero the most significant 8 bits!), various improvements to mem.c (eg. mem_invalidate_range() is now faster), fixed resetting PCI on soft reset, and made the KBC soft reset again.
