A quick look around, I noticed /dev/mtdblock2 it where is seems the

/dev/mtdblock0 is the nolo 'Nokia Loader' code and /dev/mtdblock1 is the
config partition?
/dev/mtdblock3 is the initfs?
Yst this is correct. Kernel lives in /dev/mtdblock2 but there appears to
be header "NOLO img" + kernel image size an kernel stats at 0x800.
2. Modifiy the initfs such that very early on, before flash is mounted
rw, have a bootmenu, much like the existing bootmenu program. This could
on selection of L4, load a kernel module which contains the L4 kernel
image, and then "take over" Linux and boot the L4 kernel.
Just a thought, can this module with L4 kernel take over already running
linux kernel but leave it running i.e. just hook into interrupt vectors,
MMU or whatever? This is how colinux hooks into running NT/XP kernel and
runs side by side with it. When done this way you won't need any boot or
linux kernel loader.
