  Consider replacing your multi-serial port card with a VoIP analog
gateway and use a pre-rolled Asterisk with virtual faxmodems, like
Elastix.  Just make sure your codec is high enough quality.  We used to
receive faxes using a dedicated Linux box with a Comtrol Rocketport and
an USRobotics MP8.  We Converted to SIP trunks and managed to get our
faxes in the SIP trunks, as well.

  This will remove the PCI pass-through from the equation.
