That's a different problem. The cylinder limit wouldn't prevent you from loading kernels up to several GB anyway. Besides, the next version of LILO will be able to go beyond cylinder 1k on many recent systems.

No need to change here. We'll need to preserve the existing functionality for boot processes following the current design for a long time.

Why bother ? There aren't that many systems that need advanced kernel features (e.g. RAID) when booting, yet lack the resources to store a few hundred kB more. Just use a properly configured regular kernel.
Besides that, I think you got everything right.
