Nope. A PCI "real" modem appears to the system as a serial port card that happens to have a modem on it, but it would need drivers to operate the serial port. A PCI Winmodem won't work either, because those are intimately tied into the Windows communications architecture (a Winmodem is more akin to a Geoport modem, in that most of the processing is done in the CPU rather than in the modem.)
either way it won't work
Not only do "most" Mac users not use PCI modems, NO Mac users do, because there is not one single PCI modem that is Mac compatible.
Also, I believe that the blue and white's modem supports Caller ID. Try Mac CallerID (http://www.versiontracker.com/moreinfo.fcgi?id=2504 )
Note also that many PCI modems advertise features (mainly voicemail) that they do not include software for, in fact, cheap PCI modems often include no software at all aside from the driver.
