Another interesting data point: if I have pseudo-device crypto *and*
FAST_IPSEC in the kernel, requests from user processes via /dev/crypto
fail (return error).  But if I have pseudo-device crypto *but not*
FAST_IPSEC, the user processes making such requests hang forever with
wait channel "crydev".

Something seems to be wrong with this driver, but I'm not sure where to
start looking.  Does anyone have it working with a 7955 or 7956 or even,
for that matter, a 7951?
