Hello,

I just checked if the problem was still present :
(after booting verbose & single-user my most recent kernel, from sources 
cvsuped yesterday)

[skipping messages from the verbose boot]
....
Trying to mount root from ufs:/dev/ad0s1a
start_init: trying /sbin/init
Enter full pathname of shell or RETURN for /bin/sh:
# kldload /boot/kernel/snd_es137x.ko
