radeon_gem_do_relocate message. Whats that?

My home machine runs F12 on a ASUS M2A-VM HDMI MB. With the changes to the radeon driver being continuously worked on, I get this message with my ATI X1950Pro card:

I presume it is harmless and only for debug purposes on Fedora.

Update: Looks like a bug has been reported on bugzilla: Bug 499335
