	Just to chime in on that :) - I've been using cpuflags to
	optimise kernel, userland, and all packages (up to kde3
	and openoffice) on an assortment of boxes including:

	K6-2/PII/PIII/sparc10/sparc5/sparc20/ultra1/shark/DEC 433au.

	The only problem I've seen is on NetBSD/sparc older compilers
	(NetBSD 1.4 and maybe 1.5) on compiling the kernel
	-march=supersparc on _some_ boxes. Of course the boxes are
	running perfectly with cpuflags under 1.6_BETA5 now, which
	makes tracking it down a little harder :)
