It does not indeed.  If you turn off the 200Hz timer for any length of
time, the AES gets very confused.  The AES uses it to time mouse double-
clicks, and even to do dispatching between accessories and the main
application.

If you're going to turn off the 200Hz timer for very long, you need to
"feed" ticks to the system to be sure that the AES doesn't lose its mind.
This is documented in the Hitchhiker's Guide to the BIOS.
