How is the out-of-the-box compatability with this card?

There are packages on the Soekris Engineering website that bundle their net* boards with other Sangoma cards:

So can the net5501 work with m0n0wall and one of these Sangoma S518 ADSL cards? How hard would the setup or retrofit be??

None of the Sangoma cards are supported.
