Remove the above and try this:

   video=vesafb:off radeon.modeset=1 radeon.dynpm=1

Then, try deleting your xorg.conf (if you have one) and do:

   eselect mesa set r300 gallium

Also make sure that mesa is emerged with the "video_cards_r300" USE flag 
enabled.  "video_cards_radeon" is *not* enough.  Your make.conf should 
probably contain this:

   VIDEO_CARDS="fbdev vesa radeon r300"

After changing this, try an "emerge -auDN world" and see if something 
needs to be rebuilt.
