I was looking into bug 909 and 910. Basically the wheel scroll action is built into KDEUI and it is hard coded.

relevant files are:

tdelibs/tdeui/ktabbar.cpp tdelibs/tdeui/ktabwidget.cpp

What is a solution, a global configuration option? or can we intercept/disconnect/handle the signal so it doesn't go to ktabbar?

Add configuration options.

Konqueror: Settings, Web Behavior, Advanced (Yet Another Advanced dialog that should be merged into the parent dialog), Text: "&Cycle through tabs with mouse wheel" (Consistent text with taskbar patch.)

Konsole: tab bar context menu, Tab Options, Text "&Cycle Tabs With Mouse Wheel" (Initial caps to be consistent with other menu options.)
