Fedora adds their own patches to the kernel, so your kernel source
from Fedora Core 3 and the one from kernel.org are not equivalent.

Did you copy in your original .config and run "make oldconfig" so the
two kernels are configured as closely as possible?

Have you chompared the .config from the old and new kernel to see if
you have the same amount of modules enabled?

Could it be that the Fedora kernels patches add or remove drivers
compared to what's in mainline (I don't use Fedora so I don't know
exactely what patches they add) ?

You are adding the -rt patchset, the changes in there could also
account for some of the difference although I must admit I don't know
exactely what changes the -rt patchset makes - I've never really
looked at it.

You are using two different versions of the kernel source and have not
told us if they are even configured identically. Frankly I'd be
surprised if they did not have their differences.
