I tried pushing the pins down - it looks better but it didn't help. Mine
only work with a lot of duct tape to keep it firmly pressed to the
motherboard. Otherwise, it slides up just a bit, enough to avoid making
contact. It seems more like a problem with the plastic

Interesting. Is there a reason why different values are used on gluglug
halt? cf http://samnoble.org/thinkpad/grub/gluglug.grub.custom.cfg:
# reset to normal
cmosclean 48:0
cmosclean 48:1
# reset boot count
cmosclean 48:4
cmosclean 48:5
cmosclean 48:6
cmosclean 48:7

I only want to use that for my tests (grub, seabios etc) so that I remain
in normal, because I can't update the normal boot status then.

There is only cbmemc, cbls and cbtime. They could be good menu options but
the output is displayed without a pager (so you can't see them as it goes
back to the menu - you have to enter a command line)
Of all of these, cbtime would be especially interesting to add a title to
grub menu, to show if the boot was in normal or fallback and how long it
took.
I'll see if it's possible to add the result of a command to grub menu
