Actually I take that back, ext3 woudln't help: except from page 4

The downside of Ext3? It's an add-on to Ext2, so it still has the same
limitations that Ext2 has. The fixed internal structures of Ext2 are
simply too small (too few bits) to capture large file sizes, extremely
large partition sizes, and enormous numbers of files in a single
directory. Moreover, the bookkeeping techniques of Ext2, such as its
linked-list directory implementation, do not scale well to large file
systems (there is an upper limit of 32,768 subdirectories in a single
directory, and a "soft" upper limit of 10,000-15,000 files in a single
directory.) To make radical improvements to Ext2, you'd have to make
radical changes. Radical change was not the intent of Ext3.

Yea so hello to some other new file system for you :) hey its the weekend,
not a bad time for downtime :)
