Again, thanks for all the tips. Trains booked to and from Grenoble. General consensus seems that relying on Iseran and Galibier being open in May would be rather fool hardy. Exciting stuff!
Russell Standring's excellent Grenoble Cycling Pages are worth checking out, and he usually updates on when the higher passes are open.
You may be lucky, the snow will go quickly if there is any consistent warm weather. The Giro is due to have a stage finish at the summit of the Galibier on the 19th of May, and one imagines they've researched when its been clear in previous years first.
