R200 Microcode detection not correct?

[jason]

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.
