Don't just sit there, buy some socks:

Upland Sports Group, Inc. (USG) announced today the launch of their custom Cycle + Rebuild Hurricane Katrina Relief Fund socks. 100% of profit proceeds from the sale of these socks will be donated to the Victims of Hurricane Katrina through legitimate organizations that are active in ongoing relief efforts.

Hell I think socks are the only bike-specific bit of clothing I don't have. Time to get out the credit card...
