Good possibility, but the documentation on HyperTransport suggests
otherwise, even for LPC bridges in this particular modern world of
AMD64. I might do the experiment someday to see if my LPC bridge is
implemented in a way that does or doesn't support enabling MCE's. Could
be different between Intel and AMD - I haven't had reason to pore over
the Intel chipset specs, since my poking into all this stuff has been
driven by my personal machine's issues, and it's not got any Intel
compatible parts.
