Some more things that required tweaking

Touchpad is recognized by the system as a generic PS/2 mouse. As a result, scrolling does not work (that I do not mind much) but more importantly it cannot be disabled while typing. Strangely enough, tapping works.
Patching psmouse.ko (using https://confluence.nau.edu/display/~cmg238@nau.edu/Recognize+ALPS+Touchpad+on+Dell+E6510+in+Ubuntu) results in system recognizing the touchpad properly (in particular, touchpad settings in KDE become available).

  1. Thanks for posting the link. However to do the kernel build on Fedora I ended up following https://fedoraproject.org/wiki/Building_a_custom_kernel.

    Currently on Fedora 15, the psmouse module is statically compiled into the kernel, so a simple modprobe of the new ko was not possible, I had to install and reboot into the new kernel.

    With that said, KDE now recognizes that I do have a touchpad, but none of the settings seem to have any effect on it. I am farther along than when I started so thank you.

  2. Dell provides a patch for the touchpad (which can be found in drivers for Ubuntu). However, this patch is for an older kernel version, and so far I was unable to make it work (truth to be told, I did not have much time).

  3. I spent a little more time with this one. Apparently it is a known kernel bug to both Fedora (https://bugzilla.redhat.com/show_bug.cgi?id=590880) and the Linux Kernel (https://bugzilla.kernel.org/show_bug.cgi?id=14660).

    The patch that was mentioned in your post only allows the touchpad to be recognized as such, but none of the settings take effect.
