BeagleBoard with hardfp

I need to experiment a bit with hardfp on the BeagleBoard, trying to
find a way to move compatible packages between Angstrom and Ubuntu.
I found this page via Google:
   http://www.angstrom-distribution.org/feeds/next/ipk/eglibc/armv7a-hardfp/debug/Packages.stamps
which implies that there has been some work already done on this.

Where can I find the Angstrom sources (recipes, etc) that were used to
make these feeds?

Thanks
