However, you will likely be able to at least greatly reduce the risk of such firmware-based reinfection by running an entirely different OS as your host OS. For example, if you use Windows 7 for your day to day activities, and boot Knoppix only when you want to do some online banking.
In my opinion it is quite unlikely that persistent firmware malware would be able to infect across two different operating systems, meaning that your local software environment is pretty safe once again. This is assuming that the firmware malware is not autonomous, in that it requires the help of the OS to do nasty things, which they all to my knowledge do. One could imagine an infected network card that sends traffic reports to the bad guys regardless of the OS that is running locally, but we're starting to reach the limits of what is possible.
It is also possible for a virus to disable Deep Freeze. If it can be disabled, there is no reason a virus can't do it. Of course, this would have to be a targeted virus, but if a few 15 year old kids can figure out how to disable Deep Freeze, there is no reason any normal developer can't do it programmatically.
