The problem is not so much that the bolt won't spin, rather that it won't come out. It's pretty common that the front bolts seize into the control arm sleeve if they haven't been moved in 13 years.
With the back nut removed, ideally the bolt should simply slide out. Reality is somewhat different, and even with a BFH it refuses to budge. My only option was to cut the suckers out.
It's all behind me now though. My method was probably somewhat similar to that of what I imagined Chris did.
1. Remove rear front control arm bolt (this one should come out smoothly - at least both of them did for me )
2. Waste 2-5 hours breaking sockets, bruising hands, getting PB blaster in your eye, etc trying to get the front bolt out.
3. Take an angle grinder or reciprocating saw to the arm, cutting it so that only the small part of the arm extending from the problem bolt remains.
4. By this point, you should be able to get the bolt to atleast spin, because you will have better access to hit it with a BFH.
5. Remove the nut on the back of the bolt
6. Spin the bolt (it will move what remains of the control arm with it) so that you have an optimal angle to get the grinder in there.
7. Grind away on the rightmost bushing, spinning the bolt as necessary for clearance. Try not to breathe in the burning bushing...and take it off as soon as you can so you don't breathe in more than necessary.
8. Once you get through the bolt, pry the sleeve towards the gap you have created with the grinder. This should give you sufficient clearance to cut the other side of the control arm bushing.
9. Install new control arm
