Starting with MY 2001, the fuel pump contains a non-return valve to keep fuel pressure high when starting. This was introduced to reduce exhuast gas emissions during a cold-start, and not to solve any problems. Nice theory, though.
For the record, I have a '99 V6 (5 years, 60K miles), and an '04 (1 year, 9K miles) and have never had a cold-start problem even when below 0 degrees.
