Bingo! kldload snd_ess does in fact also load snd_sbc and snd_pcm, and
it all works. Apologies, I was mislead by the fact that in the kernel
just has "options pcm" without any further fuzz.

So yes: some machines require a kernel with PNPBIOS even when sound
modules can be kldload'ed. I presume these are typically boxen without
knob to disable the PnP BIOS.

Still I wonder whether sound on -CURRENT will do on such a box...

Thanks all for sharing!
