Try this:
edit /usr/src/linux/include/asm/param.h and change HZ to 100 (instead of
1000). Other folks here can perhaps comment on the side-effects, though
I've noticed few I couldn't handle. Perhaps a divide by 0 warning with
some programs that "guess" at the HZ, but other than that...
You'll find it only happens when the processor ACPI module is loaded. Go
figure.
