Note, this commit means that i moved the commit over from
tip:x86/urgent into tip:x86/apic - i.e. with a 2.6.30 merge
date. When exactly was this regression introduced? I think this
code never really accepted the MSI settings from the firmware,
so changing that behavior might affect a lot of systems.

So i'm uneasy about applying this fix this late in the .29
cycle, but marked it for -stable backport so it could hit
2.6.29.1 if it stays problem-free.
