>Description:
	GENERIC kernel doesn't boot with GPT sliced disks.
	It seems that no device like ad0p1 gets created when ACPI is loaded as module.
	As soon as I recompile a kernel with device ACPI everything is fine.
>How-To-Repeat:
	Set up a i386 machine with GPT sliced disks and try to boot GENERIC (which
	has GEOM_GPT in the kernel but not ACPI). After watching errors like these:
		/dev/ad0s1a: FILE SYSTEM CLEAN; SKIPPING CHECKS
		/dev/ad0s1a: clean, 93566 free (1142 frags, 11553 blocks, 0.9% frag)
		Can't stat /dev/ad0p3: No such file or directory
		Can't stat /dev/ad0p4: No such file or directory
		Can't stat /dev/ad0p5: No such file or directory
		Can't stat /dev/ad0p3: No such file or directory
		Can't stat /dev/ad0p3: No such file or directory
		/dev/ad0p3: CAN'T CHECK FILE SYSTEM.
		/dev/ad0p3: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY.
		Can't stat /dev/ad0p4: No such file or directory	
	recompile the kernel with device ACPI and see the system booting fine.
