If accepted, this patch would be the forth move of pci_bios_mem_addr
in seven months.  The last three (which tracked commits to bochs) are:

d9104ffe085bffdd35196b70672883cc6af8808f
d1c4d6461468550e0639b6bc08eaa48da4617f4e
8740e3a8325de8e6453da1db1b011c036d021789

I need some background on why the address can't be at the end of
memory.  Why can't VBE use a PCI bar like a real device would?
