You could do busy waiting with udelay/mdelay from linux/delay.h. But i guess you want some function to be called every <short intervall> In my opinion there's no other way then changing HZ, which is not a risk but your cpu will spend more time servicing timer interrupts, also wrap-arounds will occur more often. Maybe you want to check out Real Time Linux ..
