OpenCV on beableBoard

hi everybody!

I would like to embedded a detection programme on an mobile platforme
and I have choose an beagleboard (BeagleBoard-xM).
I have Ubuntu 11.04 on my computer and I use OpenCV 2.3.
I would like to know if I can have good performance with this board,
because I need to have an almost real time detection.
I also want to know if there is some wiki or someone who can help me
to instal OpenCV on the BeagleBoard.

thanks a lot.
