*Hi Martin, *
Check <* cat /proc/ioports* > prints all ioport addresses.
you should check the following function for good details.
#include <linux/ioport.h>
int check_region(unsigned long start, unsigned long len);
struct resource *request_region(unsigned long start,
unsigned long len, char *name);
void release_region(unsigned long start, unsigned long len);
*Regards:*
