Subject: [34-longterm 114/209] Input: i8042 - add Sony VAIO VPCZ122GX to nomux list

  =====================================================================
  | This is a commit scheduled for the next v2.6.34 longterm release. |
  | If you see a problem with using this for longterm, please comment.|
  =====================================================================

[Note that the mainline will not have this particular fix but rather
will blacklist entire VAIO line based off DMI board name. For stable
I am being a bit more cautious and blacklist one particular product.]

Trying to query/activate active multiplexing mode on this VAIO makes
both keyboard and touchpad inoperable. Futher kernels will blacklist
entire VAIO line, however here we blacklist just one particular model.

[PG: mainline commit for blacklist is 73b14484fb686252aaf4aac4fa65b4]
