Correct, for systems which don't use premultiplexed drivers, we're
resorting to a userland muxer (not the gsm0710muxd though, but rather a
clean implementation based on other code). I'd love to see a kernel
muxer, really. While I don't think it makes a difference on GPRS, it
might improve system performance on EDGE or UMTS a lot.

I think it'd be great if you could upload your code somewhere.

Do you no longer have an Openmoko device? If not, I could arrange to
ship you one -- it may have problems, but at least the GSM would work.
