The GGI project has done this in a module specific way. A module load
time parameter can be used to force a base0 - base4 address range to be
mapped to a region specified by root, regardless of how the bios maps
it. There's source at www.ggi-project.org. The spefici file you could
take a look at is i386.c which is the kernel module interface, located
as ggi/driver/kernel/linux/i386.c in the source three.
