Actually, if your modem is integrated into your sound hardware there
might be an ALSA driver for it. Intel chipsets have these, and so do
some ATI mobile chipsets. Then a partly-binary-only daemon from
SmartLink can be used in ALSA mode, regardless of the make of your
modem, to provide a software stack on top of the sound card driver and
do normal dial-up.
Conexant, SmartLink, et. al. don't really make modems for laptops, as
near as I can tell. Modern laptops have basically a special soundcard
(for which there are several open source ALSA drivers in the kernel)
hooked to a phone jack and these companies provide the proprietary
software stack that modulates the input (from, say, pppd) on a pseudo
TTY (Linux) or serial port (Windows) into audio to be run through this
card and out the phone line. That's why the Linuxant driver costs
money--they don't even make the hardware their software is supposed to
be "driving".
