 maybe.  there are further "reserved" pins which are entirely up to a
PCI-e card manufacturer to use.  in the case of the Huawei EM775,
_yes_ four pins are used to do a McBSP / SPI style digital audio

 but it is NOT part of the pcisig specification; they merely make use
of the "reserved" pins, thus making compatibility between 3G PCI-e
modems a bit of a problem.
