No. You're running off down a path that has no benefit to either yourself or FreeBSD in the long run. What you want to achieve is best handled by the use of ACPI; you can read the raw tables with acpidump and look at the resulting device tree with devinfo. Consider investing time and effort where it will yield the best return. Futzing with pnpinfo is not a good example. = Mike -- To announce that there must be no criticism of the president, or that we are to stand by the president, right or wrong, is not only unpatriotic and servile, but is morally treasonable to the American public. - Theodore Roosevelt To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
