Just out of curiosity I checked phpinfo (Suhosin Extension 0.9.23). Do these settings seem okay?
suhosin.post.max_array_depth 100
suhosin.post.max_array_index_length 64
suhosin.post.max_name_length 256
suhosin.post.max_totalname_length 256
suhosin.post.max_value_length 65384
suhosin.post.max_vars 2000
I assume that's the section you're talking about.
