Please do, reply to my private email in the header. If it boots on 12 it 
  is good enough for me. But I could probably strip it further to make 
sure it would fit a smaller memory footprint.

s/cfg/img :-)

I wonder if there is something else on the system that produces broken 
kernels. Bad compiler or mismatched libraries.

I guess I do not need xen installed to compile the kernel, right? Maybe 
I should try to ssh to my home machine (which I know is 100% fine) and 
compile on that. It it also faster..

But anyways, please send me the binary kernel and the system.map and I 
will test it.

Thanks!
