Wow! Great news.

How difficult do you think is to separate the releasable stuff from the
rest?

The best way is to send separate patches for changes that are logically
separate, like:
*) a patch for the arch/hppa directory (codegen and trampoline)
*) a patch for io-layer
*) a patch for 64bit or endian issues in metadata
*) a patch for the test cases
*) a patch for configure.in and the build issues

If the interp changes are both endianess/64bit issues and performance
enhancements, do you think you can split them? It would make it easier
to merge in the changes that way.

Feel free to ask any questions on this list.
Thanks!
