I'm too using ld-2.17:
GNU ld (GNU Binutils for Debian) 2.17.50.20070426

gcc version is 4.1.2.
The linker script is a nearly unmodified linker script version from a
x86-64 ld. You can output the linker script the linker normally uses
with 'ld --verbose'. Maybe a diff between yours and the one used in
U-Boot can give some light?

The 64 bit version of the linker script mainly increases some
alignments and changes the link address to 0x400000.

Here's the diff to the original linker script I used:
