I emailed Sentelic the other day to ask them if they plan on releasing Linux drivers for their touchpad - here is the response I got:

Dear Allan,

Thanks for your letter of 12 September. We apologize for the problem you had with us. Our technical support team has already dealt with it and will release a new Linux version of driver for our touch pad about the end of September. We greatly regret the inconvenience caused by this.

Yours Sincerely,

Sentelic Corp.
So, users frustrated with tap-to-click might be in luck!
