I had heard that some Chinese folk were using the joke site "Elgoog" to serve as a kind of proxy. The hole may have been plugged by now.
http://www.alltooflat.com/geeky/elgoog/ is a joke site; you ask someone if they've tried the Google mirror site, and point them to it....it's a joke on the work "mirror", of course.
But today they have a plea at the bottom of the page, with a Paypal donation link: "Hosting a Google mirror for 1.3 billion Chinese people isn't cheap. Please help us out with our bandwidth costs."
