    kernel - Hack the DMAP size
    * Make the minimum DMAP size much larger.  This is a hack to accomodate
      EFI framebuffers that have been mapped to very high physical addresses.
      Due to the early initialization, they must use the DMAP.
    * Fixes booting on modern intel-based HP laptops.
