It's still not in Debian "Lenny". I'll investigate later, but I think 
the problem is much more basic than a theme or similar.

My desktop screens are on a SPARC with everything else connected by X on 
VNC and I'm quite simply not changing that.

Here's what I'll do next: remove 2.2.3 and 0.9.26 from my desktop system 
since they're not reliable, reverting to 2.2.0 and 0.9.24 which have 
served me reasonably well. I'll do my best with my limited time and 
understanding to help pin down the 0.9.26+SPARC problems but if I can't 
then I'll quite simply stay on 0.9.24 on all platforms.

I already know that I can duplicate the gtk2 speed problem over X using 
Debian "Etch" which is what's installed on my desktop system, if I can't 
duplicate it on a local screen I think that helps pin the problem down.
