NEWCARD causes kernel panic when modem is inserted

From: Maxim Sobolev <sobomax_at_portaone.com>

Hi,

I found that -current panices when I am trying to insert 3Com
3CXM756 modem card. This doesn't happen when I am inserting my
older modem card - TDK DF3000, in this case it is detected
attached as sio without any problems. Following is postmortem
gdb debugging session, please note that for some reason gdb
gets it wrong and displays pccard_read_cis() as a faulty function,
while in fact the 0xc019ceb6 address belongs to the
pccard_scan_cis().

-Maxim
