There is no way at all to turn off quotas. Otherwise users could exceed their 
quotas by creating many EAs.

You could create a filesystem with large inodes (-I option of mkfs.ext3), in 
which case small EAs are stored inside the inodes, and so don't cause block 
allocations. Otherwise, you'll have to increase quotas.
