I would have sent a PR, but unfortunately (well, rather fortunately
for me) I do not have access to those offending notebooks any longer,
but instead got one with a Phoenix BIOS, which seems to work fine.

I know someone who has a MobilePRO BIOS notebook, but I cannot say
when I will be able to lay hands on his machine again, let alone do
some debugging with the NetBSD kernel.

Sorry for that, I'd liked to have helped.
