The root password should be the one you created when you installed the
rootsh package. If you forgot it, then...

I have not tried it, but you might be able to use a rescue initrd like
the one described here to gain access to your rootfs:
http://wiki.meego.com/ARM/N900/Using_Rescue_Initrd

There are also a few things that could have helped, had you installed
them ahead of time, like backupmenu, or if you have NITdroid or MeeGo
in a dual-boot environment you might be able to use them to edit your
file permissions.

Good luck!
