Currently it seems that the only bug that's blocking xM is bug 613855. With that fixed xM will probably work fine.
If you want to test I generated a kernel at http://people.canonical.com/~rsalveti/maverick/kernel/linux-image-2.6.35-19-omap_2.6.35-19.25rsalveti1_armel.deb with the proposed fix for bug 613855. With this kernel it seems that everything works fine, besides a kernel trace that shouldn't affect much:
