the mods in the kernel allow you to write IR-codes to /dev/ir :
example code from displayserver.c :

struct empeg_ir_write {

          int type;

          long ircode;

} *irdata;



irfd = open("/dev/ir", O_WRONLY|O_CREAT|O_TRUNC);

irdata->type=0;

irdata->ircode=1;

rts = write(irfd, irdata, sizeof(irdata));

if (rts == -1 )

          perror("Writing to IR device.");

close(irfd);

the type is actually allways zero
