I was wondering about this too, as I used to use a handy replacement for the `update' daemon, called `mobile-update' (at http://www.complang.tuwien.ac.at/ulrich/mobile-update/ ) but this no longer works now that the bdflush daemon has vanished, or the kernel interface has changed or some such. Any ideas? I would love to get this working again with a 2.2.15 or 2.3.x/2.4.x kernel, as it made a fair difference to the battery life and a large difference to the noise generated on some machines... Dave
