Excellent, thanks a lot for the step-by-step instructions. If I arrive
early enough tomorrow morning I'll give this a shot.
Oh, and I've taken the liberty to copy-paste your instructions to
http://wiki.laptop.org/go/Disassembly_top. While the section doesn't quite
fit the rest of the page due to the missing photos I think that's the best
place to put them so others can find the information in the future.

Hehe, just like one of the workshop participants here on Monday who proudly
announced that he had reassembled the whole laptop again - only to realize
that he forgot to include the back-cover and therefore had to take the
whole upper half apart again. ;-)
