That's the patch I'm using at the moment. The changes for 2.6 are similar (with
an additional one for dnetd).

With that in place I can run X sessions for several hours at a time but they
still can die. I haven't done any more investigation into this. I suppose what
needs doing is to strace the Xserver for a whole day, or until the problem
happens and then have a look at the last few (hundred!) lines.
