I changed this to 30 now, btw, since 10s turned out to be too short on
many systems.

As mentioned you can change the time readahead keeps running. In the
long run I think the right approach for the desktops is to simply
re-login after a reboot everybody who was logged in before it, and then
activate the screen lock by default for them.

The other thing I'd like to make happen is that we can collect
username/password when we prompt for the HDD key, and use that first for
decrypting the harddisk and then for authenticating the user. THis would
require us to keep HDD passphrase and user passphrase in sync, but that
should be totally doable and is probably deseriable anyway...
