Thanks! I didn't think of ioctl at all, but it seems to work just fine, I just tried it on my H2O.

EVIOCGRAB does the trick, nickel no longer sees the touch events.

Of course the downside is, pickel wait-for-hit no longer sees them either, so I have to handle touch events myself.

Or maybe not: pickel is actually happy with a fifo instead of the real touch device. So I can write a small C utility that grabs the touchscreen, bounces all the data into a fifo, where pickel wait-for-hit then picks it up.

trivial code snippet I used for test (grabs touch for 60 seconds or until you ctrl-c)

int main(int argc, char *argv[]) {
    int fd = open("/dev/input/event1", O_RDONLY);
    if(ioctl(fd, EVIOCGRAB, 1) == -1) {
        perror("Failed EVIOCGRAB grab");
        exit(1);
    }
    printf("Grabbed touchscreen...\n");
    sleep(60);
    if(ioctl(fd, EVIOCGRAB, 0) == -1) {
        perror("Failed EVIOCGRAB release");
        exit(1);
    }
    exit(0);
}
