hey.  Mathieu Lonjaret reported exactly this problem with
an ibm eserver with the same chipset.

i don't recall if he got it working.  does it work for you without simnow?

one silly idea.  any chance legacy usb is on.  system management mode is
direkt aus der hölle.  does 9loads top-of-memory match the e820 scan?
