Ok.  If SA_SAMPLE_RANDOM is not in
the call to request_irq, you can put 
it in.  A trivial (but untested) patch: 
(if outlook doesn't mangle it)

I have not tried your patch.  but this is in cpqarray_init() and it is only 
called when the driver is initilaized.
How is the entropy-pool further updated ?

Thanks

Manon
