Afer lots of swearing and fiddling around forever with a non-functional Wlan card (following a mischievous upgrade from Nokia), I installed the b-e drivers and finally my N900 is a working unit.

Thanks a million! I just have to find out how to make the drivers the default (don't laugh at me, I am getting there in spite of being a noob, learning by doing).

And: Yes, I've donated. I couldn't have seriously used the N900 without these drivers.
