addendum - basically the argument is: we should kexec conservatively -
i.e. we should leave as few assumptions and hw changes around as
possible. So restoring the MSI state is fair enough as a robustness fix,
even though only kexec to older kernels is affected.

clearly 2.6.26 material, not 2.6.25.
