x32 syscall behaviour is supposed to be distinguished by a high bit set on %eax, not by the syscall table index. The choice to start numbering from 512 seems to be intended to avoid a collision with other additions made in parallel, not to provide a permanent distinction between native x86_64 and x32 syscalls.

Ah, right, perfectly normal procedure then, just with a much bigger gap than I'm used to :)
