Ha!  Yes, it would seem the obvious thing to do - but as you say, at least
you get told what borked and may even be able to remove it without
stopping the machine.  Sometimes.  Or at least you get a nice lunch from
your Sun reseller.

The current crop of power4+ boxen is reputed to even be able to recover
from a failed CPU without a restart.  Not *always* one imagines, but
usefully often enough for the banking mob to get sweaty over the feature. 
More importantly though, IBM seems committed to supporting all this
goodness under Linux too  (though not BSD I fear - sorry Bruce)

Now if these vendors could somehow eliminate downtime due to human error
we'd be talking *serious* reliablity.
