Since alsa-lib config file describes how to best deal with the
combination of chips rather than a particular notebook name
(especially given same device can have different names from different
vendors and at the same time some vendors are ill-minded enough to
call different devices with the same name) it would seem more logical
to stick to the chips' names.

Mark, do you have some idea how to solve the issue at hand (having
dmix on this netbook by default) better? Is quantity of maximum
simultaneous playback/record PCM streams already queryable by the
userspace? Somehow it happened that adding per-device config file was
ok during all these years, is there a better way now?
