Hi, I agree with that, there seems to be lot of code duplication between i386 and x86_64. By the way, x86_64 does take care of suspend/resume for hpet, it is done by
linux-2.6/arch/x86_64/kernel/time.c:timer_resume(struct sys_device *dev): hpet_reenable()
on i386 PIT driver goes out of way when HPET is detected So it seems that there is lot of work to do to remove redundant code.
