    boot - Hack workarounds for chromebook 'SeaBIOS' issues
    
    * The google seabios hack to boot legacy-mode only reports 16MB of extended
      memory.  For now, enforce a minimum of 64MB.
    
      This was preventing the loader from being able to load the kernel+modules.
    
    * Fix a bug in biosdisk.c to force bounce buffers if the target buffer
      is beyond the segment address limit, in addition to checking for
      64KB boundary crossings.
