I have put a build of GENERIC containing my framebuffer and ADB changes on ftp.n.o at: <ftp://ftp.NetBSD.org/pub/NetBSD/misc/rjs/mac68k-GENERIC.bz2> the extra files and patches needed to build it are at: <ftp://ftp.NetBSD.org/pub/NetBSD/misc/rjs/mac68k-20151005.tar.bz2> The cuda driver hasn't been tested at all as I don't have hardware.
