Rick, I forget the steps, but last year, or even before that someone on the
groups showed how to use the device tree compiler to decompile a blob file.
So if you have the dtb for Angstrom, it should be decompilable.

The post in question was in relation to the sdcard operating in 2bit mode ?
versus 4bit. But maybe someone else here recalls how to decompile dt's
using the device tree compiler ?

Then if you can not get your hands on a device tree compiler old enough. I
do have several images ( including original Angstrom- updated to 3.8.8 )
that should do the trick. SO at minimum if i can remember how, and had the
binary file i could decompile it myself, and give you a pastebin link to
the source.
