MBP: I cloned my old HD to a new (larger) one, and OS X only sees the older (smaller) space.

The disk in my MBP was upgraded from 100GB to 250GB. They used a hardware disk to disk copier that just cloned the drive, bit for bit. Now, I want to grow my 100GB partition to fill up the new space, however Disk Utility only sees the drive as 100GB. I know there are some $100 utilities out there, but I am a geek and want to do it for free.

We have tried to boot into Linux, use tools like gParted (which see the full drive, but only let us create a 128MB partition), rEFIt (to sync the partition maps), etc. but to no avail.
How do I reset the partition map so that it sees the full drive?
