>Description:
Insert Xircom CreditCard Modem 33.6, CM33 PCMCIA card, I get:

    pcmcia3: card irq 9
    pcmcia1: CIS version 2.1
    pcmcia1: CIS info: Xircom, CreditCard Modem 33.6, CM33, 1.00
    pcmcia1: Manufacturer code 0x105, product 0x100d
    pcmcia1: function 0: serial port, ccr addr 800 mask 3
    pcmcia1: function 0, config table entry 1: I/O card; irq mask 8ebc; iomask a, iospace 3f8-3ff; memspace 0-1fff0; powerdown
    pcmcia1: function 0, config table entry 2: I/O card; irq mask 8ebc; iomask a, iospace 2f8-2ff; memspace 0-1fff0; io8 io16 powerdown

    pcmcia1: function 0, config table entry 36: I/O card; irq mask 8ebc; iomask a, iospace 2e8-2ef; memspace 0-1fff0; io8 io16 powerdown
    com1 at pcmcia1 function 0: can't allocate i/o space

I figured the "com1 at pcmcia1 function 0: can't allocate i/o space" 
didn't look good, but tried a tip com2 anyway, and I get a panic:

   vm_fault(0xf08adf00,0,1,0) -> 1
   kernel: page fault trap, code=0
   Stopped at     _comopen+0x33:   movl   0x70(%esi)%eax
   

>How-To-Repeat:
Insert Card.
>Fix:

in sys/dev/pcmcia/com_pcmcia.c, function com_pcmcia_attach, 
#if 0 the following statement:

                if (cfe->num_memspace != 0)
                        continue;

This is the diff:

Thanks to Chris Demetriou who helped me find & fix it.
