For just about everyone, a value of 2 seconds or less is just fine.
For those with tape drives, changers, and (less likely) cdroms, a
long delay after reset is still quite necessary.  There are two knobs
to adjust this, and I'd like GENERIC to remain compatible.  It's 15
seconds, not 2 minutes.  You get a longer delay that that just trying
to set up the inital page tables on a large memory machine!
