From what I know, off the top of my head, all of the mods from 1.5.2 SHOULD work perfectly with 1.5.3. The only update from 1.5.3 is a minor change, the mods should work.
Taken directly from the 1.5.3 post, by one of the admins:

Version 1.5.3 contains a fix to a security risk to those servers with magic_quotes_gpc turned off. It currently is not publicized on any security sites and was found internally by Christian Land. Even though this vulnerability does not effect every server we reccomend you treat it as a required upgrade. Due to how small of a fix this is, all mods for 1.5.2 should work with it.
Notice that last part,
Hope this helps!
