Found on Dell's Website. Here are the release notes
Input Alps GlidePoint/StickPointer, Driver, Windows 2000, Windows XP, Multi Language, Multi System, v.220.127.116.11, A03
Improved usability with wide-aspect liquid crystal display (LCD) panels.
I have installed this on a MICRON XKE and it works great with Microsoft IntelliMouse Driver V4.01 on Windows XP. I have only tested for a few hours however. Unlike Version v.18.104.22.168 (a driver I previously posted) this driver maintains all settings when booted.
I have been using the previous release to this driver (v.22.214.171.124) which also worked well with Microsoft IntelliMouse, but seemed to slow mouse response.
