Worked around update frequency troubles by modding my xorg.conf, this isn't blocking my upgrade any more. Thanks!
Some questions remain though that you may want to look into:
* Removing the HorizSync and VertRefresh lines from the generated xorg.conf and letting Xorg autodetect those values resolved the update frequency problem for me.
* I had to add "1600x1200" to the Display subsections of Section "Screen" to get 1600x1200.
