Probably ~~ 2^64 times as hard.

64 bits can be cracked in hours using eg ?Net Stumbler.
Last time I read up on this (over a year ago) 128 bits was theoretically
crackable but in practice was believed to be essentially secure to all but
perhaps the experts with a serious grudge and very serious computing power.
Has this changed since then?
