I got the opportunity to test your getbootstate on a second, completely newly reflashed N900 (fiasco and eMMC), without any other modifications involved in the boot.

I just wanted to say that it works perfectly on this N900 too, with almost completely stock settings (this is not, however, your latest update that fixed the problem with time, but the one I compiled earlier - but that shouldn't make a difference).

So as I understand it you only have to fix the format in which it saves the bootstate for DSME and then it's ready for CSSU inclusion?
