Does anyone have a link to a working root guide for the Gtab 8.9 WiFi?

Seems there's a lot of issues with the Root thread at XDA, looks like it broke after the ICS OTA. I never bothered to root my Tab 8.9 when it was on HoneyComb, and the early ICS roms had camera problems. Now, the CM10 roms have gotten everything working, but the root methods are busted for ICS it seems.
