Just tested on my i686 system with lvm2. It booted fine and everything
looks OK, in fact I haven't noted any difference.
Hooks used in /etc/mkinitcpio.conf:
HOOKS="base udev autodetect pata usbinput keymap lvm2 filesystems"
I would be willing to test raid support when it will be added. I'm not
really familiar with kernels and early userspace stuff so I can't be
much help in making a patch for it.
