Has anyone tried installing Windows 7 beta on their T400 and have working switchable graphics?

I tried, but haven't gotten it to work yet. Trying to switch from "Energy Saving" to "High Performance" under Lenovo's Power Manager's "Switchable Graphics" menu flickers the screen at most, but leaves it on integrated as best I can tell.
