My guess is that you need this in ~/.drirc or /etc/drirc:
<driconf>
<device screen="0" driver="r600">
<application name="all">
<option name="fthrottle_mode" value="0"/>
<option name="vblank_mode" value="0"/>
</application>
</device>
</driconf>
See http://marc.info/?l=openbsd-cvs&m=130679235018645&w=2
I have an r600 as well and it works very well with the above dri config.
