what's the difference between P55, H55, H57, and Q57?

I know that P55 is the only one of those that doesn't support intel FDI... but what are the other differences?
I see some extremely minor things in wikipedia: http://en.wikipedia.org/wiki/List_of_Intel_chipsets

it shows that H57 with 2 extra usb ports and 2 extra PCI-E lanes. is that it?
And H57 and Q57 are listed to be completely identical.

so... nobody knows the difference between a Q57 and H57?

Looks like these are the things that Q57 has that H57 doesn't, according to what differences I saw between these 2 pages:

Intel® Core™ vPro™ processor family
PCs with a processor from the Intel® Core™ vPro™ processor family enable IT to take advantage of hardware-assisted security and manageability capabilities that enhance their ability to maintain, manage, and protect their business PCs.

Intel® Active Management Technology (Intel® AMT)◊1
Using built-in platform capabilities and popular third-party management and security applications, Intel® AMT allows IT to better discover, heal, and protect their networked computing assets.

Intel® Anti-Theft TechnologyΣ
Intel® Anti-Theft Technology (Intel® AT) allows systems to be disabled if they are lost or stolen. The technology can be used with or without a connection to the Internet or a corporate network. Intel AT can block the OS from loading, even if the hard drive is replaced or reformatted. Intel AT can also be used to disable access to data encryption keys and block access to valuable data on the hard drive, even if the drive is moved to a different system.

Intel® Trusted Execution Technology◊1
Intel® Trusted Execution Technology for safer computing is a versatile set of hardware extensions to Intel® processors and chipsets that enhance the digital office platform with security capabilities such as measured launch and protected execution. Intel Trusted Execution Technology provides hardware-based mechanisms that help protect against software-based attacks and protects the confidentiality and integrity of data stored or created on the client PC.

Intel® Virtualization Technology (Intel® VT)◊1
Intel® VT combined with software-based virtualization solutions provide maximum system utilization by consolidating multiple environments into a single PC. With Intel vPro technology built into desktop PCs, IT can remotely manage systems while providing highly secure, centralized, and virtualized IT services to end users.

Q57 can be simply put as Intel's Business-class Chipset for 1156 Processors so it has features unique to vPro, etc, as Athadeus put.
