G'day
There are a few references in the 3.5 rules to a character buying levels as a cleric of are particular deity, for example banning a cleric who has offended his or her god from buying levels as a cleric of that deity until he or she has Atoned. This hints at the possibility of a character multiclassing in clerichoods of different gods. I don't think this was intended by the rules, but it does sugggest some fascinating speculations.
In the first place, cleric class abilities (except for armour, weapon, and shield proficiencies) are granted by gods, and held during their pleasure. In most cases I expect that I would rule as a DM that a character would not be able to serve two separate deities at once, and therefore would have to be out of favour with at least one of them at any time. I would even be skeptical of claim that a single character could serve both, say, a Chaotic Neutral deity and the abstract principle of Chaos at the same time. The upshot would be, I think, that a 3/3 Cleric/Cleric of two different gods would be effectively a 3rd level cleric of one of those gods with extra hit dice, BAB, saves, and skill points. His or her spellcasting and turning would be way behind a straight-up 6th-level cleric, and I don't see a player wanting to play such a character. Perhaps it might be interesting for an NPC with history: defrocked cleric of one god starting over with another or with an abstract divine principle. The only ability I am doubtful about is the doubled first-level bonus to the cleric's two good saves.
Now here is a question. Suposing that in some strange circumstance the DM decided that two gods would not mind a pet cleric serving both of them. Would it be grossly unbalanced for a character to have the domains and spells corresponding to being a multiclassed cleric with separate levels in being the cleric of two different gods or of a god and an abstract divine force? How does a 3/3 cleric/cleric stack up against a 6 cleric? Or a 5/4 cleric/cleric against a 9 cleric? Would spellcasting be weaker? Would doubled domains and gross saves make up for this? Would you rule that turning was based on the higher level or the sum of the levels? Or that the character got two lots of turn attempts at possibly different power levels?
