Oh, that's a nice way to keep the dictionary, but I think you'd still
run into the issue where there are multiple platforms to match. In
this instance, the arch could be i386, i486, etc. I don't know if a
dictionary works well for that. As stated elsewhere in this thread, I
think the most straightforward would just be a series of conditionals.
This is what I'm using right now:

import platform
import re
_machine = platform.machine()
if not re.match("i.86", _machine):
       skip.append("xf86-video-geode")
