I did this (`sysctl machdep.uc_devlist' is not empty), but neither /kernel.config nor /boot/boot.conf are created. "Who" writes these changes into /kernel.config and/or /boot/boot.conf? In 2.2.8 stage2 boot (boot2) was reading info from /kernel.config, and `dset' was used in /etc/rc to update the /kernel.config with UserConfig changes. I think you should test this on 3.1-RELEASE(STABLE) and re-open the PR.
