What are the chances GRUB/syslinux could be taught to look at a few
special CPU flags (can you fetch the important flags from real mode?)
and only present "compatible" (as determined by config arguments, not
GRUB/syslinux poking into kernels) boot options? That would help the
LiveCD case as well. You could have both 32-PAE and 64 kernels on the
CD and choose at boot time, although that would take up a large amount
of space (so maybe not feasible for LiveCD).
A com32 module could be written without too much trouble for syslinux,
but space on the live images make it kind of a moot point (imho) as it
seems better to ship more applications as opposed to more kernels on the
live image
