I'm not really sure how best to handle this. The smbios table can be
larger than the current space reserved for the f-segment (when there
are a large number of CPUs).
There is actually space in the f-segment that is unused, but not given
to the malloc_fseg pool. That space could be given to the pool -
though the available space will still vary depending on the code size.
It's also possible to relocate the 32bit "run-time" code to high
memory which would then free up more space in the f-segment (at the
cost of some high memory being reserved from the OS). As above,
though, the f-segment is still fundamentally limited by the 16bit code
Also, it's possible the code could try to use the f-segment if there
are less than say 16 cpus and use high memory when more cpus are
