Subject: make SO_KEEPALIVE optional for TCP NFS mounts

Recently I ran into the problem of high ISDN bills :) and finally found
that a NFS mount using TCP makes use of the socket option SO_KEEPALIVE to
see if the connection is still alive;  the default is 2 hours so my ISDN
router dialed every two hours.  So I'm asking if it is possible to
add a mount option for TCP mounts to turn off the keepalive on the
socket?  If yes, I'm willing to add this myself, provided I don't
have to have it done until tomorrow :)
