Note that unlike in HEAD, this defaults to off and must be explicitly enabled by setting the loader tunable hw.pci.mcfg=1. - Add support for the Intel 915GM chipsets by reading the BAR. - Add parsing of the ACPI MCFG table to discover memory mapped configuration access on modern machines. - Port the memory mapped config acess to amd64. On amd64 it uses the direct map. - For config requests to busses not listed in ACPI's min/max valid buses, fall back to using type #1 configuration access instead. - Add a workaround for some K8 chipsets that do not expose all devices on bus 0 via MCFG and fall back to type #1 for those devices instead.
