Yes, well, another way to use like:

	#ifdef __KERNEL__
	
	#include <linux/config.h>
	
	#ifdef CONFIG_IA64_HP_SIM
	# define HZ 32
	#else
	# define HZ 1024
	#endif
	
	#else
	
	#define HZ 1024
	
	#endif

Adding HZ=1024 for userland seems ok for me even if CONFIG_IA64_HP_SIM
is defined, but any problems?
