SPF only covers the envelope sender, so it should be possible to set that to something that validates with SPF, keep the RFC822 From: header as it is, and maybe(?) include a separate Sender: header matching the envelope address.
As Cameron says, Sender: isn't necessary - just have the envelope address be bounces@ or something and it should be fine. This is how SPF and (eg) mailing lists interact.
