Hmmm... well so far I can't even get the installer to work. It hangs
on the language selection screen (I tried the Ubuntu AMD64 port as
well, and it, not surprisingly, hangs at the same point).
I've tried just about every combination of boot parameters, with no
luck. Should I just be using the i386 installer and go with a EM64T
kernel instead?
