It doesn't... Which makes me wonder if my problem may be with the boot
itself.
Once I have my zImage properly (?) compiled, I create an ACE file thus:
$ xmd -tcl genace.tcl -jprog -board ml405 -target ppc_hw -hw system.bit -elf 
zImage -ace Kernel26.ace
But then nothing happens when I boot with it.

You mean svn head ? Yes.
Something escapes me here. I pull the complete kernel git tree from Xilinx 
and
when I menuconfig it, it removes the Xilinx additions ('nonexistent symbol 
')...

I'm not very knowledgeable of the kernel organization, so I don't know what
this means, but I imagine there's a relation between 'XILINX_ML40x=y' in
.config, Kconfig which holds the help text and the .h/.c driver files
themselves. How can I check that the whole package is sane ?

One detail, I'm not doing 'make' from the kernel directory, but from the
buildroot directory, this way I'm sure it's compiled with the appropriate
cross-compiler and environment. Maybe targets such as ml405_defconfig are 
not transmitted properly from one make to the other. Anyone who knows 
buildroot care to
comment on that ?
