I had the same thing happen in a fork dropout a few years ago.
Can you get a hacksaw blade on it and cut then file it flat as close to the frame as possible?
Centre punch dead centre, then drill it out in progressively larger bits until you're almost there.
If you're lucky the remainder might smash out with a large flat screwdriver, then run a tap through it to clean the threads out.
If not then it's time to use the right sized drill and retap it.

[QUOTE 3024026, member: 9609"]If it's a steel bolt into an aluminium frame it has probably bonded itself into place with corrosion, probably explains why the head snapped off in the first place. Could be very difficult to drill out, unless the drill and the frame can be held with in some sort of jig, the drill will wander into the softer material.
What size is the bolt and do you have a picture of the sorry situation -[/QUOTE]
this is exactly what happened in my case and here's how i resolved it:

Managed to get my stuck bolt out at the weekend by starting with a 2 mm drill bit and working up to a 4 mm bit , i then had to tap the remains out with a punch as the threads had stripped .
I will be mounting a rack using a nut and bolt that side now.
