Could any xchat-xsys users that are not afraid of using an experimental
patch unmask version 1.9.3 with /etc/portage/package.unmask and see if
the /video output gives you the right information.
If I get 10 reports that it works, I'll unmask it and unleash it on ~x86
and ~amd64.
(Any other arches will most probably miss out on some CPU-related
information, tell me if at least /video works, and I'll try to get it
supported fully).

What the patch does is getting rid of the lspci dependency. Upstream
reports that it can cause stale processes that will not disappear until
X-Chat is closed.
The code in question has been replaced with a sysfs tree-walker that
should find the AGP video card in any system. If anyone out there has a
PCI-Express adapter, I'd like to know if this code finds it or not.

Thanks,
Tony (Chainsaw).
