It's NOT a run-time option, it's a compile-time one.
Choosing LEGACY_START_ADDRESS=y hardwires the physical address at which
the kernel itself will be loaded as 3MB (actually 0x310000).
On the TITAN-based machines (DS15/DS25/ES45) the console (SRM) lives
in that area, so the base address of the kernel needs to be AT LEAST
8MB and better 16MB.

Yes, one could have differently-configured kernels available via aboot
"slots" on a single netinst CD/ISO; it's just a matter of building the
kernels (as appropriate) and managing them.

As I would have expected... ;-}
