Dual Monitors with Matrox DualHead2Go DP on 13" Unibody MBP

So I've seen a few strings around this issue but no real answers...

Matrox DualHead2Go should be able to to run 2 x 19" monitors (1280x1024)easily. I've downloaded the Powerdesk software from Matrox and hooked everything up but just can't get near the resolution needed. Has anyone seen a step by step solution anywhere? The display properties in OSX won't go bigger than 1920x1200 and I need 2560x1440. The graphics card is well capable of doing it as I've previously been running a single 27" screen. The best I can do is 640x480, which just *****. Clearly there is a settings/set up issue with the MBP and the Matrox. Has anyone manged to set up a DualHead or even TripleHead with the MBP?

I should add that I have multiple issues with this product. I'm not the kind of person to return a product normally, but I have experienced the following:
* NO success in getting ANY triplehead mode working under Mac OS X 10.6.2 or the just-released 10.6.3. This is especially frustrating as the triplehead modes work fine on the SAME MACBOOK PRO under Windows XP!
* When moving the mouse, cursor jumps by a random amount every 3-4 seconds, but ONLY when using iTunes or QuickTime Player.
* Strange drop-outs of pictures from all connected displays for a couple of seconds -- occurs seemingly randomly, approxiately every 20-25 minutes.
* After waking from display sleep, sometimes only the left-most display starts up, and I have to physically unplug and re-plug the other display. I have tried physically swapping the displays, in case it was an issue with the display, with the same results -- so appears to be an issue with the triplehead2go box.

To me, given the fact that the box works just fine under windows xp (bootcamp) on the same mac, it looks like these issues are really issues with Mac OS X. I would speculate that the Mac's displayport driver is buggy.. certainly, buggy in dual-link modes. The ongoing issues that users of the Apple Displayport to Dual-link DVI converter have had would seem to confirm this -- many of the issues experienced by users of that converter are the same issues I am experiencing with the matrox box.
