[ale] Modem identification and connecting

[agcarver+ale at acarver.net (Alex Carver)]

Nope, it was completely clean and so was the cardbus socket (the wifi
card works in both cardbus sockets).  Three hours of google searching
led me to blacklist the smsc_ircc2 module which woke up the serial ports
(both the on-board and the modem) and everything started working.
Somehow that module (used by the IrDA module) causes issues with serial
ports on many laptops.  I don't know why, that's probably more google
searching.  I don't need IrDA support (though it would be fun to play
with since I have several IrDA enabled devices) but it would be nice to
find out why smsc_ircc2 messes things up.
