No ideas.
Check that you use last svn-revision.
Whats the error code (see errno) ioctl returns?

This my code is working quite well

    #include <stdio.h>
    #include <sys/types.h>
    #include <sys/stat.h>
    #include <fcntl.h>
    #include <sys/ioctl.h>
    #include <linux/types.h>
    #include "linux/sigma/quasar.h"

    int main(int argc, char *argv)
    {
        int fd, st;
        struct quasar_osd_screeninfo osd;
        osd_command_t cmd;

        fd = open("/dev/fb1", O_RDONLY);
        if (fd == -1) {
                perror("open:");
                return 0;
        }

        st = atoi(argv);
        if (st)
                cmd = FB_OSD_SHOW;
        else
                cmd = FB_OSD_HIDE;
        if (ioctl(fd, FBIO_OSD_CMD, &cmd) != 0) {
                perror("ioctl:");
                return 0;
        }
        return 1;
    }
