Pretty much we put the code that sets up the DRI from the DDX into the
server/radeon_dri.c which miniglx builds into the dri.so, you can sorta
compare that file and the radeon_dri.c from the radeon DDX driver.
However I'm sure most of the pcie code made it over at one point but I may
not have published it.. and have probably since lost it..
