The preliminary indications I have indicate there are problems.
I applied the 2.4.23-G4 patch from Ingo with the same results you had, ie the the mmremap offset and Makefile failures. Compiled and rebooted the kernel on a test machine.
XFree86 4.3.0 with the RedHat patches now fails to start with a SIG11 error. Turning off exec-shield (echoing 0 to /proc/sys/kernel/exec-shield) enables XFree to start normally.
So it would seem that something changed with the mremap changes in 2.4.24.
