Hi Jose,
I began to port our modifications done for the 64-bit support against 
the new version of e2fsprogs Ted posted at the beginning of the week.
Note that it is *just* for test use as it breaks the backwards 
compatibility.
I did a few tests with a kernel 2.6.17-rc7 and it seems to work, at 
least mkfs, debugfs and fsck tools.

Get the new version of e2fsprogs at
ftp://ftp.kernel.org/pub/linux/kernel/people/tytso/e2fsprogs-interim/e2fsprogs-1.39-tyt3
and apply the patchset in attachment.

Hope this helps,
    Valérie
