DINGUX: Attempt to fix the new code for this backend

It seems in the gsoc2010-opengl branch, the dingux port was not anymore
updated at some point, so some changes that were made in general did not
make it till here. This is my attempt to fix at least the most obvious
problems, but without being able to compile it, all these changes should
be very carefully reviewed.
