Hmm, emulating Solaris/PPC wouldn't be that easy, as it is little-endian,
as far as I know anyway, and running programs with different endianness isn't
supported currently.
On the other hand I don't see AIX as a problem, apart from the POWER
compatibility. Slab code shouldn't be a problem, since programs can get the
complete 4 GB address space for their use (well, currently apart from the
topmost page due to limitations in the vm system). And segment registers
aren't user visible anyway.
