I'm seeing a very similar problem. But mine isn't fixed as of Oct 28.
I considered filing a separate bug but this one looks so similar, I decided to add info here.
Keyboard events work in "bursts". Very frequently, the keyboard echo is delayed.
Related: my keyboard repeat is set to be fast (50 per sec) but it pauses every 12 chars for about half a sec.
It looks like xorg is too loaded/busy to handle the character interrupt rate.
If I disable desktop effects, the situation becomes a bit better but keys are much slower than 50 chars/sec as they used to work under hardy and KDE-3.5
