I know just enough about serials and ttys to be dangerous. I'll try to
tweak the 8250_pci.c code and see if that can work with this driver. I'm
currently running a 3.6.11 kernel on this box. I'll work on that version
first. Then I should probably update to the latest 3.7 release and port
it there.

I can only test the card I own:

  Systembase Co Ltd Device 4d02

If it works with this driver, then I'm happy and I'm all for shooting
the sb105x. Heck, I'll pull the trigger myself.
