Bug Description

On oneiric, rngd refuses to start:

  $ sudo /usr/sbin/rngd -r /dev/null --hrng=tpm --fill-watermark=90% --feed-interval=1
  Unsupported kernel detected, exiting...

In util.c, the function kernel_mode() (starting at line 57) attempts to determine whether the kernel is a valid supported version. It has not yet been modified to take kernel version 3.0 into account.
