I still think that we should probably be moving away from > acpi.ko rather than towards for other reasons. I noticed that and I used mptable instead, which seems to do well enough for the job. Please keep in mind that I am not trying to promote acpi.ko at all. I just want to make sure acpi.ko can be built and loaded without builing and installing the whole world/kernel for i386 to test new ACPICA. :-( Any way, I will just revert sys/modules/acpi/Makefile change, then. It should be a reasonable compromise, deal? Jung-uk Kim
