CompactPCI has a hot swap feature or requirement not sure
which. We probably would make hot swapable boards if we
went into CPci.
Would it be a bad idea to maintain a list of boards that need
shutdown info?
A) Split the pci array into two units, one for __initable info and
one for shutdown needed info.
B) Copy sutdown needed info from the __init array to a dynamically
allocated array as they are discovered.

Bloat is always bad. :-)
