OK, good that we're at least on the same page.

I'm not sure that I can do anything about differences in speed between  
Quartz and X11. They should be in the other direction, of course, but  
I don't know that for X11 Apple hasn't bypassed the Cocoa/Carbon  
layers that gdk-quartz is forced to use. In any case, if it's a gdk- 
quartz issue, it's not something that I can fix anytime soon. Gdk- 
quartz is part of GTK+, and while the GTK+ developers will claim to  
support Quartz when pressed, they are not actually doing anything --  
not even applying patches supplied by other developers. (e..g: http://bugzilla.gnome.org/show_bug.cgi?id=588449 
)

To further isolate the problem, though, you said in your OP that the  
scrolling problem wasn't noticeable on 2.2.9 (vs. 2.2.9.1).
Is that truly the case with both issues? I didn't see a scrolling  
problem using the 2-finger drag, just the lagging thumb when dragging  
it. Is scrollwheel/2-finger-drag scrolling the only sort that you find  
slow?
