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 .. -- Amancio Hasty hasty@rah.star-gate.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
