Ok, that works. I will put a bug report into redhat so they hopefully 
will integrate that into the latest code. Why they are releasing a -18 
for F15 I don't get, when it doesn't even have any code changes.

So to sum up, amd 6.1.5 patched as below works fine on F14 kernel's with 
autofs4.

The amd redhat supplies does NOT work, in fact, it doesn't even load 
properly with autofs enabled.
