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
