It's not so easy. The officially available Linux kernel versions don't support 
MSI on PPC4xx right now. The 4xx-MSI driver is missing. I have such a driver 
in my queue. It still needs some cleanup and porting to the latest kernel 
version though. I'll send it to you in the next few days.

BTW: This question is off-topic here on the ELDK mailing list. Please use 
linuxppc-dev for such questions in the future.

Best regards,
Stefan
