Actually I'm not looking for testing (I can test fine on my own laptop :)
I was just hoping someone with docs could tell me "MSI is documented to be
broken on 945GM" or "Oh yeah, 945GM requires you to set SECRET_MSI_ENABLE_BIT 
in register FOO before it generates MSIs."

As I said, it's not a big deal but I'd sort of like to know whether my
MSI enable hack at least has a chance at working before I try too hard
to get it working.

Thanks,
  Roland
