For random numbers, maybe take a look at srandom32() to set the random
seed and random32() to get a random 32-bit number.

Thanks, that works fine.

Do I _need_ to call srandom32() before using random32()?  Calling
rmmod and insmod a few times, it appears to be seeded already.

Assuming I need to call it, what can I use to seed it?  I don't have
time() from time.h anymore so this doesn't work:

srandom32( ( unsigned ) time( NULL ) / 2 );
