I added a line of code to get some info about whats going on.
DRM_INFO(Loading radeon_cp_microcode, not the R200\n");
Do I need do a build world to install this? I remeber the radeon
modules used to be in a folder where you could just type make install to
install the them by their selves if you updated/hacked them. I don't
see a makefile in the folder so this is why I ask, and make says no
target to make.
