[ltp] thinkpad t20 modem

[James Mckenzie]

Matt:

These are all PCI devices and can share an IRQ.  This is not usually the 
problem with the LT modem device.  Usually the problem is either 
incorrect memory location for the device or the wrong port selection.  I 
think I had to specify the correct port for the modem on my A22p system.
