The SystemACE in the linuxppc-2.4 kernel works fine for me on
our JSE board. We keep a lightly used ext3 partition for root,
and a FAT partition in the beginning for boot and ACE files.
The Xilinx HAL, though ugly as sin, has not given us trouble.

We use a PPC405GPr with the SystemACE connected to a peripheral
bus. No VIIPro here. this is surely different from the ML300,
yet it works.
