I had a patch for this in my 2.2 kernel tree,
originally from wingel@ctrl-c.liu.se, but I
didn't have time to port it to 2.4. I've been
using it happily for about 2 years on the NFS
server which is too close to my bedroom. The
only annoying side of the problem is that when
you incidentelly do an NFS access and the disks
are down, you have to wait a few minutes before
they spin up, especially with raid. I once
failed a CD burning session from the NFS server
because doing something else simultaneously
woke other disks up, which hung the NFS server
until they were ready.

But it's definitely interesting, and missing
in 2.4 IMHO.

If you want to try it for your 2.2 tree, I
can send you the patch.

Cheers,
Willy
