Also, make sure that we don't load the analog stack if there are no analog inputs defined in the board profile. Thanks to Michael Krufky for providing information on the various ways different Hauppauge boards can be configured.

Thanks to Paul Thomas for providing sample ARM hardware that was experiencing the oops (tested on the at91rm9200 based LinuxStamp). Thanks to David Brownell for providing insight into the ARM memory architecture.
