At least you get them inserted ;) When I try to modprobe rate_control I 
get the following:

Dec 22 15:27:48 kirk kernel: 80211: module license 'unspecified' taints 
kernel.

ieee80211_rate_control_register

Most probably caused by my 64-bit-kernel. I have to dig into that.

Nevertheless, I would address this sort of hangup to jbenc and probably 
jgarzik on linux-kernel (or better netdev).
