	SH4 support is in the netbsd-current source code tree (we even have a
	kernel configuration file for Dreamcast).  just try to grab
	netbsd-current tree, via anoncvs/sup/whatever methods.

	they need to be officially published from Sega (and Sega does not
	seem to be very happy about doing that...)
