Yes, 1024 cylinders is the real limit.  The limit in bytes depends on the
disk geometry.

>(assuming yes) does FreeBSD fully support a bootable FreeBSD partition

FreeBSD supports booting from kernels anywhere on any disk given that the
possibly-remapped BIOS cylinder number(s) (for all data in the kernel and
all metadata associated with the kernel) are < 1024.
