we could expand init_memory_mapping to support direct map for them...
with needed prot.
or use set init_memory_mapping() + set_memory_wb() directly.
but that is only for 64bit x86
also someone is talking about to have 6 pcie display adapters on 64bit
system. and every card will have 4g ram.
32bit could use fix map for 1G or 2G mapping.
