Fedora Core 1, is Oprofile installed, if not, how to do it?

[<gre...@pl...>]

Hi,

Probably a really stupid question but here goes.  I've installed fedora 
core 1 on my machine, it appears to have installed oprofile (all the man 
pages and stuff are there) but when I try to start it up with opcontrol 
it says

modprobe: Can't locate module oprofile
modprobe: Can't locate module oprofile
Kernel doesn't support oprofile

This is with one of the update kernels 2.4.22-1.2174.nptl  Right out of 
the box should I be able to use the oprofile that fedora core 1 comes 
with?  RPM shows oprofile-0.7cvs-0.20030829 is installed, is some setup 
required to get it going?  Are only certain fedora core 1 kernels setup 
to use it?  

I haven't tried downloading the latest oprofile and building it from 
scratch, would this be a better approach than using the one included 
with fedora core 1?  Would a kernel rebuild be necessary?

If I could use the version that comes with fedora core 1 it would be 
helpful simply because I need to get it running on a number of different 
machines.

Any help would be appreciated.  Thanks!

Greg
