They come from udev running vol_id, but they're actually printed by code in glibc, specifically syslog (udev logs to syslog, which apparently thinks it needs to write to the screen in some cases). I saw the same thing inside initramfs on a system with a really old glibc (was upgrading it to kernel 2.6 -- finally -- and part of the upgrade was a udev install). According to the patch I saved (but never submitted anywhere: I figured the problem was the age of glibc), I removed the messages by changing udev/udev.h (logging_init) to remove the LOG_CONS flag from openlog.
