It might be worth trying to use kernel.old, verify that uname -p says
armv6hf again when booted from it, then see if you can buildworld and
buildkernel with TARGET_ARCH=armv6.  If so, then you should be able to
install those (remember to use the TARGET_ARCH=armv6 when installing
too!), and then you'll be on the new armv6 with hardfloat.  I think.
