I've just installed FreeBSD 3.1 on a laptop and it sounds like the
heads of the drive are getting parked a lot.  I've tried tracking down 
how to increase the update time, but for some reason, sysctl doesn't
think there's a kern.update.  How do I go about setting it?

Is there anything else I can do to delay writing to the drive?  Tuning 
a filesystem parameter, or some sort memory cache parameter?

Thanks for your help.
