DIMM relocation on Tyan S2885

I have an Opteron machine based on the Tyan K8W S2885 mainboard which is
equipped with 8GB of RAM (8x1GB DIMM). The BIOS is mapping  the PCI/AGP
devices into the address space immediately below 4GB and so
consequently, I am losing access to nearly an entire 1GB of RAM. I've
spoken to Tyan about this and they acknowledged that it it is principle
possible for the BIOS to remap the DIMM presently located at 3GB to 9GB
but that they have no intention of including this option in their BIOS
as it "penalizes 32-bit OS's that cannot use more than 4GB." 

So the question to the panel is: Will LinuxBIOS solve this problem for
me? The task this machine was purchased for really does require as much
RAM as possible.

Thanks in advance,

Matt Harvey
