Ru@freebsd.org walked me through it in Oct. Do: make TARGET_ARCH=i386 DESTDIR=/i386 world kernel You also should be able to build alpha on x86. One word of warning -- you need to unhook sysinstall from the build, as it depends on x86 specific bootblocks laying around, or something like that. My memory is rather vague..
