I think that this is a well known and still unresolved issue.
As far as I know nobody has been able to get a microphone working with any
non-OSS version of Skype via ALSA emulation.  That's exactly the reason why I
started looking at PulseAudio.
Not sure if it's worth debugging alsalib input issue further.  It's open source
after all, so a determined person with proper test environment could go to far
length.  But I am sticking to pulseaudio for time being.

BTW, to update on the link that you quoted:
- the kernel patches are already in head and stable/[78]
- libasyncns in the ports
- pulseaudio-libs is in the PR db
- for pulse communication via local sockets one has to create an additional link
in ~/.pulse directory: "${hostname}:runtime" which should point to the same
location as "${hostname}-runtime" created by native pulseaudio daemon.  This is
because of different pulseaudio versions.
- input and output sources have to be set via pulseaudio config, e.g.:
default-sink = oss_output.dsp4
default-source = oss_input.dsp1
in client.conf.
