Too lazy to check if they patched the shadow file like on 5.3, but, in case they did, what ixtab said, except with a recent USBNetwork package, it will let you in with anything as the password [or, nothing, even, just enter] (provided you're using the default config: no SSH over wifi). Barring that, what knc1 said, the telnet daemon will *always* get you a root shell straight away.
