Use this to test the kernel:

grep "changes from state" /user/src/linux/net/sched/sch_htb.c

If it isn't there, then 2.4.27 does not include the latest.  Should it
be the case that 2.4.27 doesn't include this text, you should post that
here for posterity.  You DID google "2.4.27 LARTC", didn't you?!!

The most recent stable iproute2 is 2.6.9 so yours should be fine; it is
the one I use.

You MUST compile your own kernel after setting PSCHED_CPU in
linux/include/net/pkt_sched.h so patching HTb if needed is No Big Deal.

If your tc returns error messages for things that should work, use the
binary from Devik's site.
