I cannot remember the rule, but the RAW specifically says that summoned creatures do not impact XP gained. But you are talking about a house rule after all.
From what I have observed in my own games, summoned monsters are most effective in games where the DM uses alot of low HD cannon fodder. In Red Hand of Doom, Monster Summoning 3 is causing me problems with Celestial Bisons having enough damage reduction and HP to render the standard Hobgoblin Veterans useless, as well as many of the stronger Hobgoblins who just do not have magical weapons (the 4HD veterans).
Beyond that, Summoned monsters do serve quite well for two things. Setting up flank attacks for allies, impeding movement of opponents, and consuming actions of opponents. If you can summon something with a bit of staying power through AC or HP / Damage reduction, the DM either has to deal with AoO from the creatures, or use up actions trying to mop them up. And very few opponent NPC's have Cleave except as a prerequisite.
The simplest way to deal with summoned monsters is to retreat and regroup, or if you are at some distance, just ignore them and continue to shoot at the players. They are only an impedement if you have to engage them in melee.
What really annoys me about the summon monster spells is that the lists of what can be summoned just suck. How the hell is a Small elemental a comparable challenge to a Celestial Bison or Fiendish Ape?
