Years ago, Dell created the Dynamic Kernel Module System (DKMS) for Linux. It dynamically loads a new kernel module for things such as Ndiswrapper, and graphics cards. These drivers need kernel modules that most Linux distros provide as a separate package that must be matched to the kernel being installed. With DKMS, however, none of that is needed. It takes care of the module for you. Why doesn't Dell insist on Ubuntu using DKMS, a system it created to solve this very problem? Mandriva and PCLinuxOS both use it and it works very well, and saves users from this kind of nightmare.
