the previous kernel+world were built with straight "make -j2 buildworld && 
make -j2 buildkernel" with sources sup'ed around may 30

I found the following in a diff of the ident keywords between the old, working 
kernel and the new kernel :

the time window when I supped the previous kernel is between :
$FreeBSD: src/sys/vm/swap_pager.c,v 1.291 2007/05/31 11:51:53 kib Exp $
(last commit in the working kernel)
and 
$FreeBSD: src/sys/dev/sound/pcm/vchan.c,v 1.32 2007/05/31 18:43:32 $
(first commit in the latest kernel)

PS : anyway, the latest, no-sound kernel was built from a clean base (only the 
world is sometimes built with a -DNO_CLEAN flag).
