There is an easy solution for the MtGox withdrawal problem:

- open a bitstamp account, get it verified

- wait for the price between bitstamp and mtgox to be stable

- convert your mtgox usd to btc

- immediately transfer your btc to bitstamp

- immediately convert your btc back to bitstamp usd

- withdraw the usd

Only issue: hope the price doesn't move too much while it is in BTC.
