static ssize_t mousedev_write(struct file * file, const char * buffer, size_t count, loff_t *ppos)
{
        struct mousedev_list *list = file->private_data;
        unsigned char c;
        int i;

        for (i = 0; i < count; i++) {

                c = buffer[i];

oops. Can we make this die horribly on x86, just for a few kernel releases?
