I can definitely confirm this bug. However, in my case it is intermittent.
Every so often I will press Alt-Tab and the keyboard will disable. Usually (but
not always) I can mash the keyboard for a while and eventually it comes back
somehow, but that doesn't always work. It must be a KDE-related issue, because
I can still Ctrl+Alt+F1..F9 to get to a different virtual terminal (and it
works) and also Ctrl+Alt+Backspace as well (like Tue said).

This doesn't happen often and is hard to reproduce for me, but when it does, it
is one of the most bizarre and arguably most severe bugs I've experienced in
KDE. I as well am using a Thinkpad T60 but with an Intel 945GM. I'm using
Kubuntu with KDE 4.2.90, but I've experienced this bug since at least 4.1.

This is a bad one.

Having run into this bug about three times in the last day, I think I have
figured out a way to reproduce it. If you alt+tab to a window and then alt+tab
quickly back before it has loaded (choose a particularly slow window), your
keyboard should be disabled. You may need to keep holding down alt the entire
time.
