I've been messing with the driver more with more debugging info. I  
think the underlying problem actually comes from GnuPG which I was  
using to test the entropy with; its not reading from /dev/random (it  
looks like Debian is building the package without a /dev/random as a  
source). I rebuilt gpg using Debian's options, and it successfully  
generating a new key, but still not reading from /dev/random; its  
possible that the configure script GnuPG uses beleives that Hurd  
doesn't have a random so it simply setup GPG to use it.
