It's unlikely that it has to anything to do with MTRR setup -- that 
message is just a warning. Linux doesn't give it because you probably 
did not compile in the MTRR driver.
Your best bet is to post the output from booting Xen (a debug build) 
and from booting plain Linux. Also you might want to add tracing around 
smpboot.c in particular to work out wher ethe seocndary CPUs are 
getting dropped.
