Taunting me, eh? =)

Well, I did say "absolutely not recommended". 64-bit hardware of
whatever kind is without question a more appropriate solution to these
kinds of issues than such shenanigans anyway, and at this point I'm
more or less sorry I brought that up. And I'll leave the discussion
of what specific lines of hardware are most suitable for other fora. =)
