The home and limit switches are hard coded in to the sources. For many users, 
this limitation is not a problem, but for others, it is, so there is work 
afoot to address this and other issues (more on that when the time comes).

As for ignoring the homing on a single axis - If the axis with the home 
switches use HOME_SWITCH_POLARITY=0, set HOME_SWITCH_POLARITY=1 for the axis 
without a switch - As long as pin 12 is pulled high when X and Y are not 
sitting on their respective switches, Z will always be evaluated as "homed". 
Set the HOME and HOME_OFFSET parameters so that the homed axis does not sit 
on a switch and you shouldn't have any problems.
