MSI & the Kernel

From: Mutant <mutant@xxxxxxxxxxx>

I've just come to learn that pci-express equals MSI. I have tried
configuring for MSI in the kernel. And I have run without the kernel
configuration. No perceivable difference. So my question is, should I
enable MSI in my kernel? I am not using my pci-X slot.

thanks,
mutant
