[LinuxBIOS] problem about dram init

[aaron lwe]

Dear All,

I'm terribly sorry that I just found I've mistakenly configured the dram MA
Map Type, and now memtest
showed no errors. But I still have to reduce the mem size when reporting to
system through ram_resource
or filo couldn't be started.  I have disabled the integrated graphics card
and the agp, so I don't think the top
memory should be reserved for frame buffer.
