 Mine is 4.1.4, but I'm not sure it'll make a difference.
 If you send me your xen.gz kernel I can test it.

 Mine is:
 cpu0: Intel (686-class), id 0xf64
 cpu0: features 0xbfebfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR>
 cpu0: features 0xbfebfbff<PGE,MCA,CMOV,PAT,PSE36,CFLUSH,DS,ACPI,MMX>
 cpu0: features 0xbfebfbff<FXSR,SSE,SSE2,SS,HTT,TM,SBF>
 cpu0: features2 0xe4bd<SSE3,DTES64,MONITOR,DS-CPL,VMX,EST,CID,CX16,xTPR,PDCM>
 cpu0: features3 0x20100800<SYSCALL/SYSRET,XD,EM64T>
 cpu0: "Intel(R) Xeon(TM) CPU 3.00GHz"
 
 this may be what makes the difference.
