Thanks for the pointer. Maybe I can find something with that.

Indeed its the ISO_Left_Tab.

Hmm, looking at a shortcut widget, the solution might be as easy as
switching the default in kutils/kdeglobals.kcfg. Here Alt+Shift+Tab
produces "Alt+Shift+Backtab", or is that value different for different
Xorg versions? If so, I guess the best way to have a minimal fix in
kde4.0 is getting the shortcut kcm in shape (/me takes a note).
