Generally you will not be able to get Web100 patches into a Red Hat 
kernel without any conflicts.  (You're unlikely to get *any* substantive 
patch to go into a Red Hat kernel without conflict as it's heavily 
modified from the base version.)  There is a chance that the conflicts 
you run into can be trivially resolved by hand, but I can't say for sure 
as I haven't done this merge in a few years.

When I run Web100 on a Red Hat system, I usually take a Red Hat config 
and use it to build a "vanilla" kernel.  Whether this works for you 
depends on how much of the "enterprise linux" features you need.
