NMI received for unkown reason 21.

I had a PE1750 spit the following at me a few days ago:
kernel: Uhhuh. NMI received for unknown reason 21.
kernel: Dazed and confused, but trying to continue
kernel: Do you have a strange power saving mode enabled?
It repeated itself ten minutes later, after which the box rebooted
all by itself. NTPd also barfed out.
I've been running memtest86 for a day now, and no error has showed
up thus far. Dell support says "the trouble *could* be the power
savings settings in the BIOS" (emphasis mine), but as the settings
are all defaults and I've got six other 1750's from the same
batch running flawlessly, I higly doubt it. Personally, I suspect
they've got no clue and believe the kernel message is something to
pay attention to. arch/i386/kernel/traps.c clearly shows that the
"strange power saving" message is printed for *all* unknown NMIs..
Anyeay, I can't afford to flip a few settings in BIOS and put the
box back in production *hoping* it will work - I need to know that
the problem is resolved before doing so. So I wonder if anyone on
this list has had the same problem and resolved it?
The box is running BIOS version A06. I've noticed A07 is out, but
I can't find any changelog anywhere. Does anyone know what has
changed between the versions? Perhaps, if Fortuna is willing, it
could be something relevant.
