Mixing Jumbo Frames?

The last few computers I've acquired have come with gigabit ethernet NICs as part of the package.  Since I'm constantly transferring large files around my home LAN, and am a bit of a networking buff, I've decided to buy a gigabit ethernet switch.  I've decided on the SMC8508T to serve my purposes, which supports jumbo frames.  I'm familiar with the concept of jumbo frames, but this will be my first experience with their implementation.  My question is, is it possible to mix 10/100 network devices with gigabit devices using jumbo frames over the same layer 2 media?  For example, if I have two gigabit desktops with jumbo frames enabled, and one 10/100 desktop (running at 100 full) all connected to my switch, will they all communicate properly?  Or is it necessary to have a layer three router separating the jumbo from the standard?  Thanks.

You should not have any problems with your setup...  The SMC8508T (as with any other 10/100/1000 device) should automatically negotiate and handle unlike wire speeds.  The only thing you should concern yourself about is the wiring - giga should only be run on CAT5e or higher spec cable.

Well, it's good to know unlike wire speeds will not be a problem.  I was hoping someone could say a little bit more (or point me to a resource) that actually explains how the frames of varying size are actually processed at Layer 2.  If it works was part of the question, but how it works was the goal of the question. Thanks!
