Ah I see now (It seems it's impossible to get changes related to a file 
with gitweb, you have to figure out the changeset first).
That said, I'm feeling like rather not touching that stuff, and the test 
used in radeonfb even says it's not quite 100% ok, so if it's going to 
be used for not only radeons it'll better be correct.
