Launcher runs fine.
Login works fine.
Force-Update works fine.
After that, black screen. No Mojang icon, nothing.
This does not appear to right itself.
Worked fine before, only had the problem on 01/11/2012 (NZ, GMT +12).
Restarting computer did not work.
Only possible problem that I could think of was that the 'fullscreen' and 'vsync' options were causing problems, however resetting them in 'options.txt' did not fix.
Similar problems have been experienced before, however they either fixed themselves at the next run, or after time, or after restart.

You need to update to the latest LWJGL. Use the guide on the Minecraft Wiki.
Yes, thank you RibShark, that works great.
Has the issue been completely fixed, then? Or has anyone else had a problem getting Minecraft to run on 12.10 even with updated LWJGL?
Yes, take a look at https://mojang.atlassian.net/browse/MC-2067 (although I disagree that it's a duplicate; I think the person who marked it as such stopped the word "black" and didn't read it all).
This is more of a support request than a bug report. Have you tried using Oracle's JVM instead of Zero / jamvm / whatever JVM you're actually using?
