simply changes HZ from default 1000 to 100, this should improve
on-batery time, but decreases corectness of some programs using
timer a lot (even 'time' in shells is not very reliable)
+ example: played some music with mplayer, time:
+ HZ=100: real 32m24.907s user 0m4.420s sys 0m0.780s
+ HZ=1000: real 32m25.936s user 0m22.736s sys 0m7.582s
