[LinuxBIOS] Opteron caching of device memory

I'm using LinuxBIOS on my Tyan s2892. I have a device that maps a lot of
the memory space, but I'm struggling trying to get the Opteron to read and
write to my device in larger blocks. I have set the variable MTRRs in the
device driver to writeback (witnessed by /proc/mtrr), but I still get 64-bit
accesses instead of 64-byte (cache line).
