Dang it, that's my fault. Thanks for catching it Sachin.

I assumed pseries always enabled EEH, but I see now you can disable it
if you have EMBEDDED set (which your config does).

It's a bit yucky making the MSI code depend on EEH, but the only other
option would be to pull half the EEH code out - so I guess that's what
I'll do.

Does this patch fix it?

cheers
