Oops, my last reply was incorrect.  I saw COM2, and thought you were
talking about sio2.

Is there anything else in the dmesg output which would help?
Theoretically you might be suffering from the sio problems described
at http://www.lemis.com/serial-port-patch.html, but I haven't heard of
that on Dells (though of course the fact that it's a modem might
change things).  The I/O addresses are definitely funny; normally a
serial port is at 0x3f8 (primary) and 0x2f8 (secondary).  Could it be
that Microsoft is lying?

If it's the serial port bug described on the web page, it's fixed both
in 2.2-STABLE and 3.0 (which looks like it's what you want anyway).
