TL;DR: OMG I'm an idiot, just forget about those mails.

This bug is still present as of current master (3.11.0+) -- jack detection is still broken with my Realtek ALC889 on a MSI H55M-E33.

Well, in the last year or two the following additions have been made to the kernel:
- jackpoll_interval as a module parameter - turns off unsol events and
instead polls the jack connection at the interval you specify
I tried it and it didn't help, because the whole jack detection thing failed, so it only lead to fewer but longer cuts.
- Kernel automute can (for almost all cards, I believe) be disabled by
setting a mixer control named "Automute mode"
That's what I initially did, and it fixed my problem 'til PA started to see those events.
...and you can disable jack detection in PulseAudio by commenting out all sections with the jack you want to disable, the files are in /usr/share/pulseaudio/alsa-mixer/paths/*
Good to know, thanks.
Btw, just a wild theory, because I'm really not a subject matter expert: since this is a home-built computer (I assume), I wonder if this could be a very hardware near problem - i e, is the cable to the front panel chassi very close to something that gives out a lot of EMI disturbance or something like that?
You're a genius and I'm a total idiot. I never though it could be it, but apparently I overlooked the AC'97 front panel connection chart for HDA pins. Since I didn't check how I plugged it previously I won't be sure, but I'd think I did plug FP_RET_R to the SENSE_SEND pin -- which without a surprise leads to weird stuff.
I'm terribly, terribly sorry for all the noise, and for wasting your time. Sorry.
