Here's my first bit of Open Game Content.
I've seen a number of complaints on this here intarweb-thing about Drow. Namely, the complaint is that Drow are supposedly impressive spellcasters, yet the game mechanics don't support that. With a +2 level adjustment, a Drow is going to be far behind a high elf or a human spellcaster of the same effective character level. In addition to the obvious lag in caster level, there is a less obvious hit point lag - which is more notable when you consider the Drow have a Constitution penalty. An ECL 10 Human Wizard has few enough hit points. An ECL 10 Drow Wizard is going to have significantly fewer.
There are a few ways of dealing with this. One is to bite the bullet. Sure. An ECL 10 Drow wizard isn't as good as an ECL 10 Human wizard. This might miss the point, though. All other things being equal, a Drow wizard with 10 character levels is going to be better than a human wizard with 10 character levels. The point is that Drow tend to have more character levels under their belt than other races.
This answer is fine if you are only using Drow as NPCs. If you plan on including them as PCs, however, the weird balance issues begin to show up.
I came up with an alternate solution. It is based on a few assumptions. First, it assumes that Drow are racial supremacists. They've been depicted that way before. If you don't like that depiction of them, you might as well stop reading as you won't like this alternative. Second, it assumes that Drow are not intrinsically any more powerful than other races.
What do we have, then? We have a +0 LA version of Drow. It doesn't provide them with many of those abilities that we think of when we tend to think of Drow. Instead, we add on to that the ability Drow have to take levels in a revised Drow Paragon Class. Because Drow are racial supremacists, many Drow take levels in the Paragon Class - even those who would normally take levels in NPC classes.

So we can now compare a Drow Wizard 7/Drow Paragon 3 to a Human Wizard 10. The Human will have a one level advantage in caster level, an extra bonus feat and a more powerful familiar; but he will be at least a one point disadvantage in terms of spell saving throw DCs (due to the drow paragon's Intelligence boost and Master Race ability). The Int boost will also narrow the gap in spells/day between the two. Moreover, the Drow will have three spell like abilities (at CL 6), better martial capabilities, and spell resistance.
Yes, the Human is still a better Wizard. I think, however, that this closes the gap considerably.
