AFAIK the best way to get changes into the python.org tree is to file
bugreports with patches.

Patches are greatly appreciated.

There is a bug in all released versions of 2.6 that surpress the
options/preferences menu unless you install a custom Tcl/Tk framework
instead of relying on the system install of Tcl/Tk.

That's correct. The fix is in the 2.6 maintenance branch and the
Python 2.x and Python 3.x trunks. I haven't had time to backport to
the 3.0 maintenance branch yet.

Of course this works, I wouldn't have closed the bugreport unless I
knew the issue was fixed by my change (unlike whoever introduced the
bug in the first place, the if statement was introduced somewhere
during the development of Python 2.6 and never did what it is supposed
to do). I hadn't noticed before because I don't actually use IDLE
myself (or Tkinter for that matter)

The fix shouldn't be necessary for 2.5.4, unless someone helpfully
backported the bug to the 2.5.x branch.
BTW. W.r.t to Mac isssue: some of the issues mentioned above might be
related to Tcl/Tk problems, which would mean there's no easy fix for
them. I'd really appreciate if someone who actually know's Tcl/Tk and/
or Tkinter could look at these problems, I know just enough of Tkinter
to make obvious bugfixes and not enough to actually investigate these
