The GEOM work-in-progress is 64 bit clean internally and has at least one 64 bit clean partition method (EFI, from ia64) but that wouldn't be usable on boot disks without a fair bit of bootblock work and the userland tools to produce it are very raw at this stage. But one could theoretically use a 64 bit EFI layout on a large external raid and boot from a smaller disk.
