I was about to point out that accessibility users of certain linux
distributions due to necessities of accessibility support really do need
initrd's. Fedora is one instance that comes to mind just to keep speakup
working when the install is finished. Because the discussion turned in
the direction it did though, it's probably a good idea for those intent
on adding more devices to a system on a temporary or permanent basis to
download and use lspci for the pci devices and lsusb both before and
after devices get added to note the changes that may have happened on an
pci or usb level. These levels probably are going to be more
human-readable.
