Well, basically feel free to test every function. I tested a couple of
functions, but cannot test every function since my IBM T60 display's
EDID doesn't comply with the standard.
Find attached a little test program, which just test a subset of what
I implemented in terms of data extraction. For lazyness' sake you'll
have to pass it root windows and output ids. The instructions to do it
are given as comments in the code.
BR,
Leif

sorry, embedded patch was too long ;-)
