damagedspline:
since we are using the meego kernel then using the OMAP4 image should work on the N900 (the OMAP 3 build is currently broken on the build machines). Also the most recent meego image should work - i just did my install with the one from Dec 21 so i am sure that that one is OK
In terms of a prepackeaged image we will have what you want for Natty if all goes well. The Linaro guys are making a kernel for linaro-handset-plasma there is a possibility to use that
