The Philips chip is of the same basic design
as the Toshiba TX39, a.k.a. R3900 family,
if that helps.

I haven't, simply because the one example of code
that someone showed me from pocketlinux/MIPS
was really badly broken.   Note that I *did* succeed in 
fixing that function for kaffe 1.0.7 - that's part of the patch
I submitted that has been integrated into the sources.
The misbehavior of the JIT is a lot like the sysdepMethodCall
bug, but I've not had the time to pin the problem down
in that context.
