The RegConfig node (titled "Saving Window Configurations in Registers")
of the Emacs manual suggests saving and restoring frame configurations
via a register.  And desktop-globals-to-save includes register-alist by
default.

So if you make sure you save the frame configuration in a register
before exiting, you should be able to restore it after desktop-read has
reset the global variables:

(add-hook 'desktop-save-hook
          (lambda ()
            (frame-configuration-to-register ?f)))

(add-hook 'desktop-after-read-hook
          (lambda ()
            (jump-to-register ?f)))

Does that work?
