Hm. Yes, the w2sg00x4 is a Sirf based chip.

What do you need ideas for? We have that function working and
submitted year after year, but it was always rejected for API

You could have simply reused what we have proposed [1] and just
adapt it to the new API instead of writing a new driver (which
is missing some features for us).

"proof-of-concept" is misleading if you expect this to become
*the* Sirf driver and we are just invited to add some features
to that. Making our own work and proposals completely obsolete.

What I find really strange and foul play is that we are in the
review process and then comes a hidden counter-proposal by the

Well, this is FOSS...
