I think it's bootloader's problem, so there is nothing to do
on netbsd kernels.

I don't know about colo, but builtin bootloader can load
only small kernels:
so GENERIC won't boot with it though INSTALL kernel works for me.

2.x and 3.x kernels have more sections than 1.6.x, so
it might cause problem, but I'm not sure.
