Just a note to report that I can now successfully cross-compile a complete
Dreamcast build from i386 and boot and use the resulting system via IPSLAVE.

Strangely, if I burn the kernel on the ISO, I get:

	Dreamcast logo
	<pause>
	Sega logo
	<pause>
	<flash screen> <flash screen>
	[reboot]

but if netcat the exact same kernel to the IPSLAVE loader, everything works.
Ideas?  Marcus?

Much thanks to msaitoh@netbsd.org for all his work on the toolchain.
