I'm pretty sure the LCDs are the same for the two. I do some repairs on the X and have replaced a number of them. I do know the glass is slightly different but think the lcd is the same part. Look up GadgetFix on ebay and ask them. That's where I get all my parts from.
I don't know if a new digitizer would be needed or if the one from the x could be used. And as far a drivers go, the X2 drivers may have to be taken from an X2 rom and compiled into an X rom. Complete speculation though.
