With my absolutely untrained eye, it seems like I should be trying
"ideapad", "thinkpad", and "vostro". At least, those are the only places
in patch_conexant.c that seem to have anything about a "0x23" in them.
Thank you grep! :)

Of course, if anyone could cast a less untrained glance at the source and
give me some more models to try, then please!

TIA for your help,
