o.k. while looking into grub2
I had noticed during compile time
and reading posts, that -m32 is always
being called(no matter how much I tweaked the
Makefile). seeing this made me think well
if this thing is being built with -m32 maybe that might
be it i.g. 32bit to 64bit might cause some issues, but
unfortunately is not the case(building lilo you can achieve a pure64
bit build).

So after all of that still no go, but the positive side
is lilo is able to show more up the line of the boot message
error:

then the rest shown on the picture on the bug report.

Out of memory?
