I can think of two solutions:

1) Redirect kernel messages to another vt during passphrase entry

2) Change to another "clean" vt, deal with passphrase, switch back

Both approaches would break usplash, but it doesn't support user input
anyway. I'm currently leaning towards the second option which would need
"fgconsole" (to know which vt to switch back to) and "chvt" from the kbd
package.

I'll try to find time to test this approach later this week.
