I think it would be pointless to prepare universal (PPC+i386) builds of OpenJDK.

1. It will require extra complications in the build system because of different hotspot implementations needed.
2. People on Intel Macs will prefer macosx-port (which AFAIK is incompatible with Mac OS <= 10.5) rather than X11-based bsd-port
3. People usually prefer to have native binaries without unneeded arches.

However, it's possible to build non-fat ppc32 binaries on Intel Macs with OS version up to Snow Leopard. Xcode 4 on Lion is incapable of building ppc binaries.
