Small update: I've tried with the ELDK toolchains 4.1 and 4.2
(2007-01-21 and 2008-11-24). Both these fail as well, albeit in a
slightly different way. The printfs are correct, but 4.2 still has the
nand_bbt issue:

  U-Boot 2009.08-rc3-00013-g853ae64 (Aug 25 2009 - 08:28:05)
  Marvell-OpenRD_base

  SoC:   Kirkwood 88F6281_A0
  DRAM:  512 MB
  NAND:  512 MiB
  nand_bbt: Can't scan flash and build the RAM-based BBT
  Net:   egiga0
  88E1116 Initialized on egiga0
  Hit any key to stop autoboot:  0 
  Marvell>> 

The 4.1 version just hangs on the NAND printout. I've tested both with
USE_PRIVATE_LIBGCC=yes and USE_PRIVATE_LIBGCC unset, and get the same
results.
