Summary

The BDSM (Base Data Stolen Memory) register changed. Older generations are
using a 32 bit register. On newer generations a different register address is
used and the size was changed to 64 bit to permit allocating graphics stolen
memory above 4 GB. Bhyve has to detect that and properly emulate the correct
register.
