[HELP] FAQ for apache module support (mod_userdir)?

[aeg]

Is there a FAQ or reference page somewhere that lists what apache modules are currently supported or are slated to be added in the future?

I saw on one thread http://forum.qnap.com/viewtopic.php?f=32&t=3512 that mod_rewrite is done

One another http://forum.qnap.com/viewtopic.php?f=3 ... 912#p42572 there was a suggestion that future firmware might support mod_dir

Personally, I am looking for mod_userdir support so I will be satisfied if someone could point me to how to best organize my user files but IMO a general reference that answers "Is apache module XXX supported in qnap firmware release YYY" would be helpful to many.
