I don't even think distros should change the default settings of the BIOS/disk. Up to and including Fedora 7 on my laptop, the disk did a load cycle on average once every 48 seconds. Mounting the filesystems noatime changed this to once every 108 seconds, which is a little aggressive still but not too bad. Note fedora 8 will have the relatime option on by default for all filesystems.
