LUKS password prompt; suspend

Question

I just did a fresh Arch install using the Archlinux-i686-2007.11-0.4.core.iso and following the LUKS Encrypted Root how-to in the wiki to set up encrypted /, /home, and swap partitions. Everything works fine except for two issues:
1) On boot, the LUKS prompt asking for my password gets overwritten by USB-related boot messages. Hitting the Enter key gives me a new prompt and I can enter my password, so this is merely a cosmetic problem.
2) I haven't had any luck trying to get µswsusp to work. Is this at all possible with an encrypted swap?
Thanks for any hints.

This is the current patch as of 2007-11-15, cryptsetup version 1.0.5-5.

And a little script for autoinstalling, this is dangerous, make sure to have a working fallback image!
Cut and paste into a empty file, chmod +x, and ./execute as root AT YOUR OWN RISK.
#!/bin/bash
if [ `pacman -Qi cryptsetup |grep Version |awk '{ print $3 }'` == "1.0.5-5" ]
then
