Yes, my opinion was largely similar to yours. And others'. I wouldn't be rambly if I just said "ditto." 
Also, you were suggesting giving some temporary feats like a fighter's, then taking them away as soon as he atones. Which is, technically, a bit less simple and doesn't really make sense IC; how does the ex-paladin "fighter" just forget half of the skillful maneuvers he learned earlier, as soon as he atones and becomes a paladin again? Or suddenly learns them right after losing his paladinhood earlier?
It is simpler to just have some paladin levels to start with (maybe with a few levels of fighter as well, depending on how far back in his backstory he lost his paladinhood and started to need more combat practice rather than relying on divine boons to protect him), advance as a fighter during play, then do some retraining or the like via the PHB2 options as soon as he atones. Although he might lose the fighter bonus feats when he converts those fighter levels to paladin levels, it'll probably be more gradual and less sudden, as he resumes his old regimen of daily prayers and other observances and paladinish duties to avoid falling from grace again. As opposed to *pop* "Woohoo, just atoned and got all my mojo back! And......just forgot how to chop two goblins in half at the same time with my greatsword.....?"
