I think the Shark came out (long) before the footbridge.

There used to be documentation, including schematics, for the Shark on  Google still finds it, but attempts to access anything 
there time out.

Shark uses the Sequoia chip set and the PC87307 Super I/O chip, both from 
National Semiconductor.  If the 8253 is included in most (older) PCs, I'd 
expect it to be included in the Super I/O but I don't see any mention of it 
on National's overview page.
