In GeoServer 2.0.x there is no general special treatment.
There are exceptions specific to geographic data in particular cases
though:
- oracle cannot handle queries against geographic data that go beyond
   the -180,-90,180,90 limits, so we cut the bbox to that area
- on trunk where "advanced projection handling" is enabled by default
   a bbox that spans the dateline will be duplicated on the other
   side to grab that that sits in legit coordinates at the other
   end of the dateline.

This is at least what I can remember by heart.
It would be easier to help if you asked direct questions (e.g., I
don't believe you're just curious, what's the problem you're
seeing?)

Cheers
