	Only if you are running NetBSD on the appropriate CPU - currently
	'binary compatibility' under NetBSD is restricted to operating
	systems that run on the current machine architecture. (This means
	you can run SunOS/sun3 binaries on a macII, even though you cannot
	run SunOS/sun direct on a macII, (both use m68k CPUs)).

	The best option for NetBSD/arm32 would probably be for someone to
	write code to use an ix86 CPU board with NetBSD/arm32, either
	running	NetBSD/i386 directly (thus enabling BSDI, SCO, FreeBSD,
	linux, etc compatibility), or providing a similar set of
	callbacks(?) to the Aleph1 software, allowing use of Windows etc.

	I have a 486 board available free to anyone interested in trying
	:)
