A warning to everyone trying to run new kernels: the current modutils implementation does not work with the latest kernel recent. For the stable kernels everything up to and including 2.0.29 seems to work fine. 2.0.30 however does not work. For the 2.1 series there is a new modutils snapshot (source only). This snapshot is not stable enough for a public release however. For the adventerious people among us: you can find the snapshot at ftp.redhat.com in the directory /pub/alphabits.
So please stop sending in bugreports on this since the problem is known. We just have to wait until the kernel-folks stabilize the modules interface. Wichert.
