HELP! Windows changed a partition to MBR and OS X won't read it!

Basically I have three partitions on one 500Gb HD and it's been working nicely for 4 months until XP decided that it didn't want to boot anymore.

Setup is:

150Gb: Windows 7 x64 (NTFS)
100Gb: Windows XP x32 (NTFS)
250Gb: Random files used on OSX (Hence formatted for OS X use)

Now in the process of fixing the windows boot issue it's managed to **** up the 250Gb Mac partition so now Disk Utility thinks it's a MBR instead of OS X formatted.

Is there any way of getting it back so OS X can read it without formatting it?

It's 99% backed up but it's that 1% that i'd like back.

Any ideas?

Before doing anything to the partition table you should back up the rest. Since you can't access it you probably need to do a sector-by-sector image with dd or Disk Utility.
