it gets worse: on the iBook there is no ttyS* devices, and no indication 
of usb modems either. however, when one of the lines on the i2c bus is 
triggered a usb device gets 'plugged in'. from the description it is a 
modem, but it doesnt conform to ACM and in Mac OS X the driver for it is 
~300K, so i think its very likely its a software modem.

yes, the serial port would only appear after the driver had been loaded 
and downloaded its firmware code to whatever the software modem chip is.
