The Atelier UX100 ROM (P10_image_20110217_v1.09_web.exe) is available from WebMachines (link).
... from which I obtained (by flashing this ROM to my Vega) the TP (Touch Panel) Utility that I think you have been seeking...
...which I have uploaded to my dropbox.
Hope this helps.
edit & addendum: the above mentioned ROM is also now available from my dropbox...
