Just had a look at this by comparing the list of kernel modules loaded
just before cryptsetup waits for passphrase entry at boot, with
modules=most and =dep.

By that I found out, that with =most the module psmouse is loaded while
it is not with =dep.

If I add psmouse to /etc/initramfs-tools/modules, then boot also works
again with with =dep.
Strange... because no mouse or touchpad is involved... but who knows
what's going on there...



So at least this is needed on the Fujitsu Lifebook U757... maybe it
should be generally added.

Right, this is like bug #795839 but for the MODULES=dep case.

It seems like we should add this dependency to hidden_dep_add_modules. 
(Although i8042 is usually built-in on x86, so we would also need to
teach it about modules.builtin.)
