also the PCI_LEGACY find doesn't seem to be needed anymore (it's been removed with 2.6.34 btw.)
I still couldn't get 10.2, 10.3, 10.4 to work without segfaulting
I've really gone through all changes that I can think of:
completely install the system from scratch, switch from amd64 -> x86, switch from hardened -> non-hardened, down from 2.6.34-rc* to 2.6.33 / 2.6.32, conservative C/CXXFLAGS, etc.
it HAS TO BE a regression - why would it work with 10.1 and out of a sudden stop with the following drivers (I've seen this kind of behavior with the drivers from nvidia, too - so I guess the catalyst driver is getting better what helped was to wait a few months until the devs / it got fixed by itself)
