Okay, looking around a bit I found a quick workaround: from the irc log
http://www.radeonhd.org/?page=archive_display&c=radeon&m=4&y=2009&d=2009-4-15
I have read:

tormod: agd5f: ok it helped. now X starts, but the laptop freezes solid when I
switch VT
agd5f: tormod: comment out the RADEONSetClockGating() calls in
RADEONPMEnterVT() and RADEONPMLeaveVT() and RADEONPMFini()
agd5f: in radeon_pm.c
tormod: thanks
agd5f: tormod: I'll commit a fix

I found that those three lines actually were not commented in current git code,
so I commented them and now I can switch back to console / shutdown the system
properly. Whether removing those lines is dangerous (and that's why agd5f
hasn't removed them yet) or it is the right way to do it, I really have no
idea.
