  Remove GEOM_GPT.
  
  I encountered repeatable Unaligned access panics similar to:
  
  fatal kernel trap:
  
      trap entry     = 0x4 (unaligned access fault)
      cpuid          = 0
      faulting va    = 0xfffffc0000fae1c2
      opcode         = 0x28
      register       = 0x1
      pc             = 0xfffffc00004d07dc
      ra             = 0xfffffc00004d0a1c
      sp             = 0xfffffe0031875bc0
      curthread      = 0xfffffc007da237a0
          pid = 2, comm = g_event
  
  These occur when a floppy or a CD (the 6.1R install CD will do in most
  cases) is in the drive during boot.  A floppy or CD inserted *after*
  the system was booted did not give me this problem.  Interestingly
  enough booting from the 6.1-R install CD sometimes caused the crash,
  sometimes it did not.  When it did not panic an installation of 6.1-R
  was possible without any incidents.  A subsequent boot from HD with
  the CD still present sometimes(...) worked fine, sometimes paniced.
  
  Taking GEOM_GPT out of the kernel config file allows booting without
  incidents.  We do not need GPT on Alpha, so this is the easy way out.
