Officially? Take a look at http://news.typo3.org/news/article/typo3-42-alpha-1/
"Raised minimum PHP version requirement

To run TYPO3 4.2alpha1 you need to have at least PHP 5.2. This move
was necessary to use features introduced since PHP 5.0 which we hope
will give a speed impovement to TYPO3."

"What does that mean?
- TYPO3 4.2 is going to be based on PHP 5.2
..but..
- If you are using PHP 5.1 then you might be in luck... We are aware
that enterprise Linux distributions of Novell and RedHat do not ship
with PHP 5.2 yet (they both come with 5.1). Therefore, we will avoid
using PHP 5.2 any specific features in TYPO3 as long as they have not
switched."

Using 5.2 would be the best future-oriented solution.
