OK, I'll commit them this coming weekend if nobody have objections.
Linux people also are doing also reloading the countdown register of
i8254 after suspend in the same way.  It couldn't hurt, I think.

#ifdef INIT_TIMER_AFTER_SUSPEND
	save_flags(flags);
	cli();
	/* set the clock to 100 Hz */
	outb_p(0x34,0x43);		/* binary, mode 2, LSB/MSB, ch 0 */
	udelay(10);
	outb_p(LATCH & 0xff , 0x40);	/* LSB */
	udelay(10);
	outb(LATCH >> 8 , 0x40);	/* MSB */
	udelay(10);
	restore_flags(flags);
#endif
