Does Red Hat care about kernel bugs in CentOS?

[gbailey at lxpro.com (Greg Bailey)]

In the course of troubleshooting a netfilter problem, I've run into a 
scenario where I can reliably generate an oops with the netfilter module(s).

I generally like perusing the bugs on Red Hat's bugzilla system because 
I can usually find solutions or patches to issues I encounter there.  In 
this case, I couldn't.  What do CentOS users do when they discover 
bugs?  Will Red Hat consider it?  Do I file it against "Red Hat 
Enterprise 3" if I'm running CentOS 3.5?  I'm concerned if things like 
System.map, etc. don't match between the RHEL kernel and the CentOS kernel.

Any suggestions?

Thanks,
Greg
