I don't think it's related to the PPC archive, as I've been experiencing the
same thing on my Gentoo x86 box. It started happening about April, following
an xorg-server upgrade. I was forced to completely remove everything having
do to with X and then re-emerge with a downgraded version.

Since you have another server, you could always set up X11-forwarding and
run mythtv-setup remotely. Once you get it configured, hopefully most of the
regular maintenance can be done through mythweb.
