As for dynamic kernel environment part, go ahead!  It also enables setting
debug.acpi.level and debug.acpi.layer with sysctl command, not just from
boot prompt.
As for quirk part, can you port acpi_quirk.c, acpi_quirks and
/sys/tools/acpi_quirks2h.awk from FreeBSD?  It seems it's already doing
what you say in the "XXX TGEN" comment.

Cheers.

extra new line inserted, was this intended?

extra new lines inserted(without any other changes), was this intended?
