Well there was partitioning software ported over from Linux onto Maemo. Gparted. But that's because we were usually in flash and partitioning for booting onto SD. Not sure if it's different than the previous tablets (though it'd probably be closer to the n810 since the n810 had memory built in as well).

Even if there wasn't anything I believe you could just do it in any linux distro with gparted.
