FWIW, if the HW is Intel ICH based and if the BMC is doing the NMI via
the PCI slot, then the chipset needs to be configured to allow the NMI
to go through to the CPU.  I've found some systems don't enable the
chaining of a PCI NMI to the CPU NMI so then the NMI doesn't work.
I wrote some code to flip the bit in the ICH to enable it.  Note that
it appears to be a one shot so you can't get a 2nd NMI via the PCI.
