miniPCI express ? This is a new standard for small size radio modules, using PCI Express and USB 2.0 connectivity. On ALIX, only USB 2.0 connectivity is supported. Some manufacturers of radio modules (compatibility not tested by me):
Sierra Wireless
wi-fi cards using PCI express will NOT work !
SIM issue Due to an issue with the SIM switching circuit, unmodified boards are not fully compliant with the standard. By default boards will be modified to support SIM J17 only. By special request boards can be patched to support both SIM sockets, but it isn't pretty...
