When running on Intel we emulate real mode using vm86 mode.  This mode 
requires ds.base == ds.selector << 4, which isn't the case here.  You 
can modify the code to satisfy this requirement, or you can try the 
emulate_invalid_guest_state=1 module parameter (which will likely fail 
since it is not completely implemented).
