I hesitate to say this, because I'm talking to someone whose 
reputation is stellar and because my own biases may show slightly :)

	Don't - under any circumstances whatever - use Fedora on a 
production system or a system on which you want to do real work.

If you _MUST_ do it - because, for example, your hardware is too new and 
not yet supported under the Red Hat Enterprise Linux / Centos 5.4
kernel - 2.6.18-164* if I recall correctly - then it _may_ work but it 
WILL cause you some degree of instability, interesting debugging 
interaction problems and some hours/days of frustration.

Red Hat 5 was based on FC6 or Fedora 8 IIRC. Both now unavailable on the 
main mirrors.

Fedora 9 has 2.6.25 which is quite a jump. It might be worth getting the 
source RPMs and building the kernels from each of 10,11,12 but on a 
CentOS machine.

RPMForge doesn't seem to have much to help, here :(

All best,

AndyC
