switchable graphic on Montevina notebooks under Linux

[arekm]

Does anyone have new shiny Montevina notebook [1] with "switchable graphic" [2] feature and can share with us how this looks like/is usable under Linux now?

Probably not X run-time switching but I hope at least bios-time switching or maybe Linux console switching...


1. Thinkpad T400 maybe?
2. A feature that allows to run-time switch between integrated and discrete GPU in Montevina notebooks that support this.
