I use Kilauea revision 1.2 and exactly the same network card as you.
The problem is still here. It doesn't happen with other PCI-E card I have
(10G Ethernet adapter).

I have a feeling that 2 Kilauea boards of the same revision may sometimes
exhibit different behavior with the same version of u-boot. For example,
with u-boot 2008.10-rc2 that comes with AMCC CD, memory was properly
detected on one board in bootstrap option B but not detected on the another.
I had to recompile u-boot and disable autocalibration to make things work
on this board.
