[From: Frantisek Dufka]

yes, apt-get upgrade is a cake (and cake is a lie :-)

That should be possible. You need just the rootfs. On working tablet 
mount rootfs again to some other directory (to get rid of other 
filesystems mounted on top of it) and create rootfs image of it. Than 
the linux flasher (flasher-3.5 for Fremantle) should hopefully flash it.

Or at least that was it with previous devices that use jffs2 filesystem. 
There is mkfs.ubifs so hopefully it is otherwise the same or very 
similar, see here

Sadly I don't know more details sice I couldn't go to summit and don't 
have the device. Many things changed with N900.
