Greetings. I've got a Thinkpad T42p, and I am seeing very similar things. Annecdotally, if the system is booted with the lid down in the dock, it still seems to find the hard drive as hda, but if the lid is up, it sees it as hde. I haven't done this enough times to say with 100% certainty, though.
Also, Whether or not CPU-Frequency scaling works seems to be related to when it sees the disk as hda or hde.
