    The K6 at least assists in this by raising an interrupt if a process
    accesses special registers one or more task switches. Special registers
    being MMX, FPU, and possibly 3Dnow registers.

    It also sports SYSCALL and SYSRET instructions; I wonder if they would
    provide any speed gain if used with Linux or compatibility syscalls.
