On x86 architecture, Ziatech have CompactNet, which uses the 21554
non-transparent bridge. This should be portable to PowerPC, though some
work may be required:

I've done some similar work on a PowerPC, but on PCI cards and using a
very different core logic design which avoided the need for a
non-transparent bridge:

The kernel for this board passes ethernet frames over the PCI backplane
between boards. The novelty over traditional shared memory networking is
the use of I2O units.
