But I forgot to mention another thing:

I patched it with a patch for 2.6.11 to make it compile with binutils 2.22 (otherwise the assembler would complain), and, although the compilation silently ends, it probably messed up something. I will look for the same patch for 2.6.10, or to downgrade my binutils.

For those interested, the patch is that one: http://www.kernel.org/pub/linux/devel/binutils/linux-2.6-seg-5.patch
