There was a thread starting with
http://mail.openjdk.java.net/pipermail/hotspot-dev/2007-September/000138.html
on hotspot-dev.

I believe Blackdown development has pretty much stopped a while ago,
unfortunately.

Not within OpenJDK repositories, at least. Gary Benson is working on a
portable interpreter
for IcedTea/OpenJDK, so you may be able to use that once its finished.

Yes, for IcedTea (once you get set up):

For OpenJDK porters, Kelly has put together a shopping list of basics
you'll need: http://blogs.sun.com/kto/entry/building_and_porting_the_openjdk

I thnk the easiest way to find out how hard it is is to try it, and
keep the mailing lists
of the components you are struggling with posted.

good luck,
