hmm, this weekend i helped someone out to setup Gem on an intl gfx chip 
and lo and behold! it did not crash.
at least Gem claimed that it had "DRI enabled".

probably a special chip that works :-)
(he was using ubuntu hoary and once i convinced him to not try to 
install the official "Pd-extended-0.39" which has loads of unmet 
dependencies but rather the 0.40-rc, everything worked out of the box)
