You may want to try loading Raspian and seeing exactly what modules and 
X programs it is running.

Sorry, I can't give you any real advice, but I can feel your pain.   I 
love Gentoo and run it on a couple of different machines, but when it 
goes wrong, it can sometimes be a bugger to figure out why. (especially 
for me since I run a custom monolithic kernel).  Running on "unusual" 
hardware, increases the difficulty exponentially.

The toughest hardware I ever ran Gentoo on was an old Eee netbook.  I 
got it to work (and the problem-solving was fun), but it took a lot of 
effort.


Good luck!
