Well, your question was somewhat general (what are these?) so my
response was also general... But this may help:
http://www.redhat.com/software/rhel/3features/kernel/
Note that the two items that RHEL3 kernel supports and 2.6 vanilla do
not on the list (hyperthreading aware scheduler and 4g/4g mem split)
have either been added to 2.6 vanilla or have been added by RH to the
RHEL4 kernel.
