OK.

I just tried this setup on my Kilauea board. Without any problems:

U-Boot 2009.03-rc1-00050-g3aaf315 (Mar 11 2009 - 13:18:35)

CPU:   AMCC PowerPC 405EX Rev. C at 400 MHz (PLB=200, OPB=100, EBC=100 MHz)
       Security support
       Bootstrap Option C - Boot ROM Location EBC (16 bits)
       16 kB I-Cache 16 kB D-Cache
Board: Kilauea - AMCC PPC405EX Evaluation Board
I2C:   ready
DRAM:  256 MB
FLASH: 64 MB
NAND:  64 MiB
PCI:   Bus Dev VenId DevId Class Int
PCIE0: link is not up.
PCIE0: initialization as root-complex failed

Type run flash_nfs to mount root filesystem over NFS

The PCIe device used here is the Intel PRO/1000 PT Desktop card.

Which Kilauea board revision are you using? And do you see the same problems 
with other PCIe cards as well?

Best regards,
