I am very much aware of builtin bootloader limitations. Kernels that I 
built are smaller than the limit. CoLo does not have any limitations, it 
can boot kernel as large as available memory (at least that is what 
documentation said). From my experience it does not have problem booting 
  uncompressed or compressed large kernels.

What is the INSTALL kernel and how can I build one? Or where can I read 
about it?
