SeaBIOS had an explicit segment load of DS and ES in real mode.  The
segment loads in real mode should have loaded new segment bases.  I
haven't had a chance to find a reference in the SDM - do you think
this is not so?

In any case, it's a SeaBIOS bug because the segment limits and flags
would be off - the fix is commit c35e1e50.  If this also makes things
work from KVM, that's all the better.
