Yes, that's unfortunate.

You're going to need to be inventive in order to reconcile the fact that
you want to derive from text-mode while at the same time writing a mode
that behaves differently from what text-mode expects.

Eli's suggestion might work, tho it's admittedly crude.
Maybe you can set normal-auto-fill-function buffer-locally.
Or you can set auto-fill-mode-hook buffer-locally.
Or you can set the fill-column to a very large number.
Or (as mentioned) you can set phpbb-mode-hook's default to disable
auto-fill-mode.
There are probably other options.
