Okay, so I think I have an idea what might be going on.  I've attached
the modprobe -l for the various modules involved both after installation
and after uninstallation.  I note that after uninstallation, there are
still a few modules from the /lib/modules/2.6.24-16-generic/updates
folder.  Is this possibly due to an older self-installed compat-wireless
update?
Has monkeying around with non-apt packages goofed me up here?
If so, how can I fix it?
