Actually, I'm kind of late to the game with this. The LIRC server has apparently had support for this particular gadget for some years. (Of course, this also means that Irreco & co. have as well, as they are all using the LIRC server.) So, in short, your N900 can already control it.
Let me see if I can't get the same support into Pierogi. I can probably get the software to you faster than you can get the hardware to me...
