'ebtables' is just a round-all term for what became of the 'bridge 
firewalling' code. You don't need to use the 'ebtables' binary at all if all 
you want to do is apply firewall rules on a bridged system.

However, it remains to be seen whether the ebtables code would even patch 
successfully on an RHEL kernel source, plus if using a 'Real' Red Hat kernel 
is important to you, then you'll obviously not want to recompile at all.

Unless RHEL already contains the support (look for 'Bridge firewalling 
registered' in the 'dmesg' output from boot time) then you're a bit stuck.

Of course, all this talk of ebtables is now off topic =)
