Incorrect.
The RHEL kernel *is* ABI-stable for a whitelisted set of symbols. Some
3rd-party kernel modules use symbols not on the whitelist, and thus not
guaranteed stable, but it *is* entirely possible to build a kernel
module against the RHEL5 GA kernel and have it load and run fine on the
latest 5.3 development kernel, if it only uses whitelisted symbols.
And the plan is to use those whitelisted set of symbols in kmods for
EL-5 in RPM Fusion to hopefully avoid that we have to rebuild each and
every kmods for each new EL kernel.
