The Orange Ioun Stone gives what looks to be an entirely untyped +1 to caster level. You could easily houserule that things like that don't work for this case, but I think that under base rules it does.

The Adept Spirit spell (Magic of Incarnum, Clr2/Sorc3/Wiz3) is a buff that offers a short-duration insight bonus to caster level.

If you could somehow make Thrall of Jubilex count as a spellcasting class, then the Practiced Spellcaster feat wouldcould be argued to give you +4 for it, but I don't believe that's possible.

There may be other sources as well. I believe they'd mostly be temporary, but, regardless, there are at least a few effects that give generic bonuses to caster level out there.
