Compatible KDE 64 bit/Gnome 64 bit

see KDE 64 bit fix to get startx working
wifi injection works
bluetooth works
sound works (defaults to analog, see Ensonic AudioPCI ENS1371)
encrypted installation works as well (until you 'apt-get autoremove' then you're screwed)
Dell hot keys detected and work (some manual mapping required for media functionality, but that's not a backtrack problem)
