I intend to rework the MMCONF patch to map the MMCONF area into 32-bit
address space, as well as submit an updated patch for the HP DL165.  I'm
swamped in other stuff right now though; if anyone could give me some
pointers on what the best way to reserve 256M of (256M-aligned) address
space is, that would save me some time.  Either dynamically or
statically (I believe e0000000 - efffffff is often used for this).  We'd
like to hoist any memory behind this, so some method of allocation that
makes this part of the IO hole would be good.
