Are you sure it's filesystem issue? ext3 has a feature, dir_index,
which uses hashed b-trees to speed up lookups in large directories.
It's activated by default (at least on RHEL & Ubuntu, should be the
same on other modern distros). Try checking with "dumpe2fs -h" to make
sure you have it.

Also, you could organize the zone files (manually) so that they spread
over many directories instead of one.
