called once when card is attached. Solved problem with driver getting hosed when a reset takes place. Removed init_block array -- now part of malloced memory. No more static declarations left. Added code so that debug ioctl actually does something. ifconfig is0 debug will now switch on debugging code. Other general cleanups.
