Thanks for the hints and the applet... after some meddling around I 
found the magic incantations to fire up the amp / speakers on this 
laptop are to force model=acer-aspire in /etc/modprobe.conf, then using 
the applet from the URL quoted above:

./hda-verb /dev/snd/hwC0D0 0x15 SET_EAPD_BTLENABLE 2

I confirmed stereo operation...  it doesn't react to headphone 
insertion, plays audio through speakers and headphone jack in that case. 
    Didn't try 5.1 (this laptop has a 5.1 speaker set) yet but I 
wouldn't be surprised if that was trouble too.  Still this is waaaay 
better than silence!  Thanks again for the help.
