Yes, I played a little with that, looking back at what Ive got 
here the following patch worked on what I pulled about
2weeks ago byi:-
 git pull git://git.kernel.org/pub/scm/linux/kernel/git/perex/alsa.git/

I assume youe think of somehting like this which I tried earlier -
but would have been wasier if I'd have known about the mode option..

        SND_PCI_QUIRK(0x1462, 0xa422, "MSI", ALC883_TARGA_2ch_DIG),
        SND_PCI_QUIRK(0x1025, 0x006c, "Acer Aspire 9810", ALC883_ACER_ASPIRE),
        SND_PCI_QUIRK(0x1025, 0x0110, "Acer Aspire", ALC883_ACER_ASPIRE),
+       SND_PCI_QUIRK(0x1025, 0x0112, "Acer Aspire", ALC883_ACER_ASPIRE),
        SND_PCI_QUIRK(0x15d9, 0x8780, "Supermicro PDSBA", ALC883_3ST_6ch),
        SND_PCI_QUIRK(0x161f, 0x2054, "Medion laptop", ALC883_MEDION),

(Patch headers removed as patch manually editted  I appeat to got onto some on 
branch mode with git and it producing odd patches (ones with '++' at the start
 of some lines)) 

This does indeed work. I'm sorry I should have replied with this sooner, 
buts since it appeared noone was listening...
