I can't answer positively, but hardware emulation _OF_SOME_DESCRIPTION_
is definately possible running a 64 bit kernel, I ran lenny amd64 on my
MacbookPro and ran a hardware accellerated VirtualBox VM running 32 bit
Vista. I don't know how this maps accross to Doug's situation, my
thoughts would be that the added instruction set just goes unused
because the old application doesn't acknowledge it's existence?
Apologies if i'm being dense.
