All,
The V5 FX family is open for early access, and yes, it has a PowerPC(tm) processor.
I am sure that you have also read Antti's post, so he has already "spilled the beans" about which version it is.
Xilinx decided to see which IP provider had the best 'deal' for the core, so it is licensed from a third party (who licenses from IBM).
The advantage to Xilinx is that at 65nm we have the RTL code (the 405 was full custom from IBM in both 130 and 90nm). Having the RTL allows us to do much more than we have done in the past. It allows our PowerPC team to craft a much better solution for our customers.
The silicon for the FX is back, and in house, so we are very very busy with Verification and Characterization (V&C). Contact your FAE, disti, or rep, for details. Right now we have many units in ovens at 100C (and freezers at -40C) running Quake, Linux, etc. to shake out all the bugs.
Some of the nice new features are: integrated APU, 5-way crosspoint buss switch with scatter-gather DMA controllers, 64K data and instruction caches with parity (for soft error flush, and re-fetch)...
