It's not entirely clear that this is relevant, but my T400 has very odd behavior with the CD drive either disappearing or taking a very long time to probe on warm boots. Linux (or grub? I don't remember.) also has some trouble finding the root device (hard disk) on warm boots, but FreeBSD does fine. -Ben Kaduk
