It's been through several releases of Debian, ever since grub2
replaced grub (and I've been trying grub2 and reverting back to
grub-legacy every few months up until this week, when I finally had time
to sit down and fight with it for a couple of days).

I don't see any relation at all (if I did, I would have tried changing
it much earlier...).  It seems to be when the grub2 code is loading...

Firmware bug isn't unlikely, now that you point it out.  So...  it's a
Biostar M7VIG 400 motherboard (yes, it's been faithfully playing sound
cues for Las Cruces Community Theatre since 2007!) with Phoenix
AwardBIOS.
