to boot into it is quite simple if you use the uboot. with the "out of the box thing" you have now at hands from the devel repository its no problem at all, you only add a recent kernelwith the tsc patch(tell uboot where it is) and the modules to the partition.
and boot it(tell uboot which partition to boot). nicola pointed out meego kernel works out of the box. so take that if you want to test. easy as could be.

works for me for quite a while(rsyncing my stuff to part and booting).

but don't expect it to work like in "using it" though: it's a phone so first of all i want to make calls and receive calls.... maybe try ofono thats what the meego folks use.
