You can change the HZ value in linux/include/asm-i386/param.h to higher values and recompile your kernel. (My HZ is 200, which I prefer because I do develop numerical code and I want more exact benchmark times.) I think, there's nothing wrong going to 1000, if your box is fast enough. (Every timer interrupt gives you a task switch which has some overhead ...)
