A few days ago, some postings have referred to difficulties
with FC 5 and how to overcome them. Do they help in your
case?

Yes, this rings abell with me too.  It seems to be related to the fact
that programs running on recent Red Hat kernels have non-executable
stacks.

You obviously didn't find my reply to Brian B. McGuinness, where I wrote:

I believe that's what Georg referred to. This way you won't get stuck 
with Linux 2.6.15 and miss important security updates.
