Beginning of change set for making more friendly laptop configurations.

Changes _only_ take effect if `options LAPTOP' is set.

Note:  This one is distinctly dodgy. When my IDE drive spins back up from sleep
mode, it generates this `extra interrupt' condition by spinning back up and
generating an intr, though without any particular action required.  This
message coming out every time is rather annoying, and thus disabled.
However, what I'm not at all sure of is whether or not all IDE drives will
behave in the same way, or if perhaps it needs to be done in a more complicated
fashion by detecting this more involved "I've spun up and am just saying hi"
condition.  This is a simple change and easy to back out/ammend if anybody has
any better ideas.
