The boot loader is LILO from Ubuntu 7.04, so it should be fairly recent.

Attached is a boot log I get where the last patch is 
f2d98ae63dc64dedb00499289e13a50677f771f9, e.g. "Linker script for the
new x86 setup code".

The kernel is directly from "git bisect, make defconfig, make", no local
changes or strange patches applied. Build environment is plain Ubuntu-7.04.

Kind regards
