You make very good points about connector fatigue.  I was planning to
leave everything connected and only install/remove the EOMA68 card
from the micro-desktop case.  That works as long as we don't need to
test hot-plugging anything.  To my knowledge we figured the hot-plug
capability would likely be conferred by the applicable standard and
thus were designing a basic functionality test.

(Incidentally I have a dead VAIO laptop in which the power jack center
pin broke.  I really need to get that ordered and replaced.;>)
