Drupal on PAYH

[#1]

Is PHP 5.2.5 supported on PAYH? I want to run Drupal 7 which has 5.2.5 as prerequisite. The PAYH blurb merely mentions "5.2"
And barring this, are there any other gotchas (MySQL version; Apache version; ...) in running Drupal on PAYH?

The version of PHP on PAYH is 5.2.0; MySQL is 5.0.32.
