I have a R40 with a crack in the screen frame and a R40e which shuts down intermittently. I'm thinking of pinching the R40e's screen for the R40. Can anyone tell me, is the R40e screen interchangeable with the R40? (I know the video hardware is different, in fact Debian Squeeze works on the R40 but on the R40e, X won't appear, just a blank screen). cr
