Best kernel for Xilinx VirtexII Pro/PPC405 ?

[Keith J Outwater]

Hello all - 
I am designing an embedded system using a Xilinx Virtex II Pro FPGA.
Can anyone point me to the "best" kernel source tree to use ?
"Best" in this case means:
1. A 2.4 series kernel with good support for Xilinx peripheral devices 
(existing Xilinx ML300 support is fine).
2. Good stability

By default I'll use the Montavista linuxppc_2.4 tree unless there is a 
better choice out there.

Thanks!

Keith
