I think I have Fedora 7 working with 8.33.6. It is building fine and I am about to reboot to see if it worked.
However, as it stands right now Fedora 7 will NOT work with the drivers coming out later this month. In some of the new firegl code in the driver's coming out later this month it adds some new instructions, which aren't compatible with the latest release candidates for 2.6.20 (mainly to do with INIT_WORK). The packaging scripts will work for Fedora 7, but as it stands right now the driver will not work unless you compile it against a pre-2.6.20 vanilla kernel. Though if I have the time I'll see about writing a patch so these drivers will compile against 2.6.20.
Basically, 8.33.6 will work but 8.34 may not.
This is good news for now -- we look forward to testing your scripts.
