: My diffs can be found here:
: I'm not exactly sure what to put in /etc/pccard.conf:
: card "SIERRA" "A555"
:     config auto "sio" ?
: Upon booting I get:
: pccard1: using CIS quirks for Sierra Wireless, AirCard 555, A555, Rev 1
: pccard1: CIS version PC Card Standard 7.0
: pccard1: CIS info: Sierra Wireless, AirCard 555, A555, Rev 1
: pccard1: Manufacturer code 0x192, product 0xa555
: pccard1: function 1: serial port, ccr addr 700 mask 73
: pccard1: function 1, config table entry 32: I/O Card; irq mask 3fbc;
: iomask 0, iospace 3f8-3ff; io8 irqlevel
: pccard1: Allocation failed for cfe 32
: pccard1: No config entry could be allocated

Looks like you have another serial port using 3f8-3ff (which is
generally COM1).  I've had communications with insiders that say other
serial ports would also work...  I've have no time to integrate
things, however.
