Fresh Ubuntu Installation - Events/0 consumes most of cpu

[Eric Cope]

I opened up my laptop and removed the internal wireless card, eth1.
wpa_supplicant no longer pestering me. Its an Orinoco card from 2002. Its
802.11b only WEP encryption (loosely termed).

If I could get it to work with the card in it, I'd be happy, but no wireless
is not an immediate show stopper.
