Yes, if the GL driver doesn't support them.

I.e. the only 32 bit depth I see in the log is like:
  GLCaps[wgl vid 0x63 arb: rgba 0x8/8/8/0, opaque, accum-rgba 16/16/16/0, dp/st/ms: 32/8/0, one, mono  , sw, GLProfile[GL4bc/GL4bc.hw], on-scr[fbo, bitmap]]

IMHO 16/24 bit depth is standard .. more hardly needed. If so - well, there might be support by FBO.
But such huge z-buffer comparison, if needed, would imply your huge world renderer
uses immediate mode something, without any culling etc (-> deferred rendering).
The latter is not a good idea and hardly used.
