New Revision: 195045
URL: http://svn.freebsd.org/changeset/base/195045

Log:
  On special systems where the MBR and the GPT are in sync (up to the 4th
  slicei, Apple EFI hardware), the bootloader will fail to recognize the GPT
  if it finds anything else but the EFI partition. Change the check to continue
  detecting the GPT by looking at the EFI partition on the MBR but
  stopping successfuly after finding it.
