I think you're right that only the Prescott cores are using the .09 micron
process and the Northwoods are still using the .13 micron process. The
Pentium 4 Northwoods also have 512kb of L2 cache and the Pentium 4 Prescotts
use 1mb of L2 cache (the respective Celerons use less). For the socket 775,
only Prescott cores are available.
The name of the chip should also have a letter after the chip's speed to
help distinguish the lines, where they overlap. The Prescotts have an A or
an E after their speed depending on whether they are running on a 533 MHz
bus, such as the P4 2.4A, or a 800 MHz bus, such as the Pentium 4 2.8E.
The Extreme Edition Pentium 4s are Northwood cores.
Hope that helps.
