Yes you're correct those three patches will give you
1.3 on 2.4.20.

Why it's crashing on boot is another question.
That backtrace seem a bit suspicious.

Any chance you can grab the kdb patches and boot
up with kdb enabled?


Note 2.4.20 did not get a lot of 1.3 testing but
it should at least boot.
