I've always created them by hand with mknod or just copied from a working system - you know which ones you'll need, anyway.

This was actually one of the first things I checked. Just forgot to
mention it. I solved it by adding a 'ls -l /dev' in the init, and there
I found out that /dev/sda1 was named /dev/hda1. But I still got the problem.

I'm quite sure that I have compiled in all of the algorithms I'm using.
But I will add some more just to be sure. Recompiling my kernel as I write.
Thanks to both of you.

You'll get segfault if you're trying to do something like luksOpen on a
non-existing device.
At least that was the reason for me, once, when I've tried to
luksOpen /dev/sda2 instead of /dev/sda3, or something like that.
Had it figured out by putting strace to initrd and running "strace
cryptsetup luksOpen ..." instead of just cryptsetup - gave me something
like "open('/dev/sdaX', ...) = -1 ENXIO (No such device or address)", so
I had to double-check and found the mistake to be that trivial.
