I'm pretty sure that Turion review mentioned that problem, and there have been a bunch of posts (AMDZone, etc.) from people with motherboards bought before the 90nm A64 release that couldn't get the boards to boot when dropping in a 90nm part until they used a 130nm part and did a BIOS upgrade. It all just depends on the MB, and the code in the existing BIOS on the MB. If the BIOS can't ID the chip it doesn't know what to do with it. In fact, I'm pretty sure i've seen reviews + product specs on NEWEgg where it says point blank "Must use a 130nm CPU to upgrade the BIOS prior to 90nm CPU use."
The only thing the BIOS update is needed for is chip ID. As far as the board not knowing what to do with it, that's also incorrect. The informationg for multiplier, voltage, etc is sent through different bridges on the processor. The only problem you will encounter going from a 130nm processor to a 90nm is the possibility of the BIOS calling it an A64 instead of a Turion. The chip will still perform exactly as it is designed. There is nothing that board cares about when it boils down to die size. As for checking around, I have no need to. I have dropped 90nm processors in boards/chipsets that were designed before 90nm processors without a hitch.

SSE3 won't become important for a year or two, if ever, depending on how useful it is.
Exactly the reason for which it was designed. To provide a cooler running, more efficient notebook.
As for SSE3, there are and have been for a while, apps that use SSE3. They benefit noticeably from processors capable using that instruction set.
