Paul, is this OK?

I'd like it in 2.4.21 if possible.

Thanks,

Name: Qemu Kernel Patch for PPC
Author: Rusty Russell
Status: Tested on 2.4.21-pre6

D: Allow (0.1.5 or above) qemu to set the personality for emulation,
D: so files in /usr/gnemul/x86-linux get looked up before normal files
D: (this is the standard way of hooking in emulation libraries, etc).

This should say that you need qemu as well, and it should probably
include the URL to Fabrice's qemu web page.
