Buttons and Schmitt triggers


I read in the Etrax 100LX documentation that the inputs on
pa0-pa7 is TTL Schmitt-trigger. We are planning to connect
two buttons to the Etrax. If we use two of the pa0-pa7 as
input, would it be possible to use buttons that don't
have a Schmitt trigger without having problems?
(I assume that using buttons with a Schmitt trigger won't
be a problem.)
