Nice, I just installed SO last night, I can use that setting ;)
For the `df' reporting, I made this patch against Linux 2.4.2-pre4,
which does the following:
$ df /coda
Filesystem 1k-blocks Used Available Use% Mounted on
Coda 100000 1135 1438 45% /coda
$ echo 1 > /proc/sys/coda/fake_statfs
$ df /coda
Filesystem 1k-blocks Used Available Use% Mounted on
Coda 9000000 0 9000000 0% /coda
