"Severely crippled" would be if your wizard had, for example, no arms.
Being 3 wizard levels down from the rest of the party, on the other hand, is the kind of "clearly severely crippled" character I've seen in plenty of parties simply because not everybody was the same level. That is to say, the pretend kind.
LOL!! It's not that bad, really - I'm much better off that the wizard 3 levels lower, since I do have the odd Cure Light spell. I think you and I are on the same page here Doc - My wizard isn't that badly off, just overshadowed by the rest of the party.
I'm really pleased that I was wrong about epic levels - that was my biggest worry, and it sounds like I can still get to a respectable level. My damage dice might never be as solid as a wizard 3 levels higher, but there's lots of creative ways to work around that.
I think I'll start by chatting with my DM about commissioning or questing for some useful divine items, and try to play him through. If that fails, or if the DM is against it, we can always discuss more drastic measures.
