There is support for both of this card in mainline Linux-CAN:

http://lxr.linux.no/#linux+v3.6/drivers/net/can/sja1000/peak_pci.c#L64

There is no special treatment for the PCIe-version of that card and
therefore it should also work with the rtcan_peak_pci driver. But
support for 4 channels is still missing.
