no, they must provide GPLed code accepted by NXP or someone else will do
it. We can't assure quality of code we can't see.

No, a friend recently bought that card in addition to a Terratec S2 PCI
for his new windows 7 he already had. Likely totally unrelated to linux,
but on his stuff it turned out he can't use both cards at once, single
both are fine.

Sorry, can't help much yet and can't add anything new.

For now I advised better not to try with binary blobs on linux, he was
already burned enough on win7. He might try later and we will have it
under GPL sooner or later.
