This small patch makes tabs in the Baghira style center-aligned, just like in MacOSX. It requires Qt 3.2.x. The attached screenshot is in KDE 3.2b1, but I think it'll work with KDE 3.1.4 (as long as you have Qt 3.2.x).. feedback would be appreciated.
1. Download and unpack Baghira source (available here)
2. Download patch, copy it to the baghira source folder (usually called mosfet-baghira)
3. Run this command: patch -p1 < middle_tabs.patch
4. Build as normal =) (instructions available in baghira docs)
