Great, thanks!

The problem is that I use initdiskless which is run as the very first
rc.d script, even before initrandom.  It has to run first since /etc is
replaced by that script.

As a workaround I added the hack from initrandom (ps -fauxww; sysctl...
>/dev/random and so on) and the system boots again.  So I'm not really
sure if this should be fixed in rc.d or in the kernel.

Is it intentional that random(4) isn't seeded by the kernel itself now?
