I was suffering from this same problem and it does appear to be a bug
in udev-077-r1 (-r2 is now in ~x86 but I've not tried it yet).

The solution that someone else came up with (calr0x on the forums) was
to run udevstart once the system is running, this causes all of the
device nodes for the installed kernel modules to be created.
