Make sure that you've correctly enabled the "Kernel Module Loader" in the
"Loadable Mudule Support" menu.

And read the readme file in mudule-init-tools carefully.  You need to build
the /etc/modprobe.conf file with all the aliases in it.  It takes a bit of
fiddling, but demand-modloading does work.

That's OK.  It's just the kernel spamming the application developers ;)

This is a bug in rpm.  It can be worked around with:

	alias rpm='LD_ASSUME_KERNEL=2.2.5 rpm'

Christoph should be able to fix that one up.
