I can report partial success -- hotspot compiles, the jre mostly bootstraps, and Hello World runs. Anything complex appears to trigger stack alignment issues (Apple's i386 API requires a 16-byte aligned stack)

Great progress!  I note, however that this is work you did on
JDK 1.6 under the JRL, rather than on OpenJDK under the GPLv2.

If you mean to contribute this back to the OpenJDK under the GPLv2,
you'll need to fill out and send back a Sun Contributor Agreement.
You can get that form at

     http://www.sun.com/software/opensource/sca.pdf

and the instructions for sending it to us are at

     http://openjdk.java.net/contribute/

The FAQ for the contrubutor agreement is at

Thanks for contributing.
