Don't know the version with cadenzas... would be interested in seeing it though.
I think when I played it I tended to less pedal in the beginning--I may have ignored that pedal marking. You're making me think now and I wish I had the score in front of me--good question. Now I'd probably err to the conservative and try it his way--you know he occasionally had a cool idea or two :-).
On the subject of pedaling, and not to hijack, but does anyone find the pedal markings in the Chopin F minor Fantasy to be... weird? It depends on the edition you use, of course... but I'm thinking specifically of the lack of pedal in the F Major section of the introduction, and the pedaling over of the 6-5 suspensions in the triplets that immediately follow the introduction and segue to the rest of the piece. Following both of those directions literally sounds... well, bad, to me.
Did Chopin and Liszt intend their pedal markings to be taken very literally, or used as general guidelines on where in particular they thought pedal was of greater importance?
