With the exception of the device files that the installer creates so that the system boots, all entries in /dev should be created by udev. With the default configuration, when udev starts, it mounts the device file system on /dev, and populates it with the startup files. Additional files are created in responce to modules being loaded, and cold plugged devices found. Additional devices are created when hardware is hot plugged. Because the dev file system is in memory, it has to be re-created each time you boot. > Had you kudzu enabled when you put your drive in your new laptop?

Just creating /dev/dsp with MAKDEV will NOT magically get sound working. If you get sound configured correctly, then you will get /dev/dsp when ether the correct OSS sound module is loaded, or the OSS emulation module is loaded if you are using ALSA.
