I agree with Warner now if people can come up with other uses for
an "ACPI" language then I guess is okay ;however, for just restoring
vga graphic's state I think that I would find it hard to justify bolting
an interpreter in the kernel .
With respect to languages describing vga, yes there are precedence of this
type of technology for instance Thomas Roell a while back invented
his own language.
I do feel that this type of discussion is best carried out in the XFree86
mailing list ..
