I'm running the dvb-kernel drivers on 2.4.20-8 (RH9) without problem
(although my CVS checkout is a few months old). I however have a
Hauppauge Nova-CI card, so I can't comment on the Skystar support, but
I don't think the kernel is a problem.

The procedure looks fine. Just make sure the devices set up by the
MAKEDEV-DVB.sh script were actually created and have the correct
device number (212).

You need to provide this output, otherwise we can't see whether the
drivers loaded correctly.

Do a "ls -lR /dev/dvb*'" to confirm the devices actually exist.
