quote from this page:

By default, the open source radeon driver forces 1x AGP speed. Quote
from the developers:
"tuning to the highest speed possible has caused hangs on some boxes, with no
discernable pattern, so we default to 'slow but safe' whilst giving the option
to go fast if the user wants to try it."

So it loooks like a known issue to xorg developers with no workaround. :(
Thanks for the moral support. (:
