FYI, I have tested this on the latest OS, and it all seems good. I also loaded new OS on flash/kernel/initfs, bootmenu, and I was able to boot up my older versions of the OS with the newer versions kernel initfs, KDE also worked under this condition.

I had an issue when booting KDE the first time my n800 rebooted, not really sure what happened. It started up after that and worked fine after that?

I tried running new flash rootfs on old kernel and initfs and it does not work.


So there is no reason not to upgrade if you want to...
