[SATLUG] Ubuntu x86 vs x86_64 Performance

[Greg Willden]

I'm not really sure about speed issues but I'm just about fed up with
64 bit Linux.  I'm running KUbuntu on this box (AMD64) and it is just
annoying to not be able to get the third party stuff working on
64-bit.

Plus if there are speed issues then why bother with 64 bit for this
box.  It is basically a desktop machine and a place to keep all my
tunes.
