I think so, but I can't be sure of how Sony distributed the ids

SZ61 was reported to need model=vaio to have headphones working but I
could not find the ids anyway

Some commenter also reported FZ11S needed model=vaio without giving any
info and without id

Given that other model seem to need it too I think that the mask would
make sense

Unfortunately we only have this for a paying customer using 2.6.29 on
stable version, and who is happy with adding model=vaio. I found that
other had reported on launchpad, but I don't have the hardware myself to
test with kernel after July commits
