I don't remember hearing about that, so someone else would need to confirm or deny it.
Fixed two consoles recently with drives different than the original ones, so it works, unless they re-enabled it in the most recent dashboard.
One console had a defective Samsung drive, from which I extracted the key and then simply reflashed on a Hitachi, without spoofing it.
The other one had a BenQ and the guy brought me a Samsung he pulled from another RROD console. There again, reflashed the Samsung with the key from the BenQ, without spoofing it.
I reflashed both drives with stock firmwares.
One thing though - this was just a few weeks ago. I have no clue if it triggered a flag that will later ban those consoles, I haven't done the XVal checks on those (never really cared since I was reflashing to stock firmware). I don't think they've been banning during that period of time, as one guy brought me an older Xenon model for repairs, it had a Hitachi drive flashed with iXtreme 1.51 and he was able to update his dashboard and play a few games on XBOX Live afterwards. However, no clue about the XVal modification.
One possible explanation for the removal of this check might be a legal issue - I'm not sure, but it may be illegal in some countries to force you to use a specific repair center service (ie. Microsoft and its insane fees) to have repairs done on something you legally bought and own. When you buy a car, you're not tied up to the place where you bought it - you can have it fixed by a mechanic you trust, or can even fix it yourself if you have the knowledge and skills. It may be the same thing with a console - I understand it may void your warranty if you're still covered to open it, but for someone outside his warranty period, if all he does is replace a defective part with another (I'm not talking about using a modified firmware here, just stock), I don't see how they could justify banning your console from going online. This is just an hypothesis though.
