Not really, there is still highmem though that certainly a sucky solution
as compared to a 64-bit kernel.

Same loader as before - the build procedure will result in a 32-bit kernel
binary which is loaded to the same old KSEG0 addresses.

Exactly. The aim is to support both kernels without replicating the board
support code.
