Radeon 9200 SE Vmods

I've looked almost all oc'ing forums thru and I haven't found any Radeon 9200 SE voltage modding guide (or Radeon 9200 either). And since I haven't done any tinning mods so I bought a cheap card which is good for practicing. I've done lots of vcore mods for P4 Northwood CPUs and some penciling with Radeon 9800 and unlocked multiplier from couple AMD Durons but these ones are pretty easy to do. But now back to the case...

Does anyone know how to mod this card (NOTICE! This is an ATI Reference card flashed into a Hercules card)? I didn't found any guides.
And what stuff I need to get started?

Hmm, if you post high res pictures of the card and ic chips we can probably help. I'm somewhat looking for a 9200se mod myself.
