The python.org installer sadly enough can't link to Tk 8.5 because Tk 8.5 isn't available before SL and I don't want to rely on a separate install of Tk because IDLE needs to work out of the box.

And yes, "arch -ppc -i386 python2.7" enables you to import Tkinter. That's why IDLE works.

This will make it possible for 'import _tkinter' to work on 10.5 as well (if ActiveTcl 8.6 beta, with 64-bit, is installed). cf. http://bugs.python.org/issue8798

Could that work for Tk 8.4 as well?  It would be rather nice if we could have just one _tkinter extension that worked both with the Apple install of Tcl/Tk and separate installs.
