Default PCM Problem Overseas ? CASE Relearn

I have been struggling with the PCM in my Hummer H3. The car is stalling and the scanner shows 2 codes:

P0601 - Control Module ROM
EBCM Malfunction – C0240 - ABS Traction Control


We have discussed in another thread and concluded that the best solution is to substitute the PCM.

Here is the catch:

The car is overseas
No GM tech support available (talked to them 4 times)
No Hummer dealership

As far as we can tell getting and uninstalling / installing a new PCM is not that hard. However a CASE relearn has to be performed, according to pcmforless.com . A CASE relearn is only possible at a Hummer dealer. None available here in a few thousand miles.

I have a few questions:

Is there another option?
Is there a way that we can get an “original” 2006 Hummer H3 programmed PCM, with the original data that will work in any car of this model?
Is a CASE relearn really necessary?
Can the data in the faulty PCM be stored in used in a new PCM?
If the data is just reflashed in the faulty PCM, does it need a CASE relearn?
Will I have to bring a mechanic from the US with all the equipment needed to fix the car?
Does anybody know anyone at GM / Hummer that can help me? I will gladly pay for the services/consulting.

I would like to stick to the technical aspects and solution to this problem, here in this thread. If you are curios about how, where and why it all happened, please look at:

Thanks, I appreciate any help.
