With the foolowing patch, I have identified the weird file:

diff -Bbu /src/linux/fs/exec.c.orig /src/linux/fs/exec.c
--- exec.c.orig Wed Mar  7 21:47:33 2001
+++ exec.c Wed Mar  7 21:47:20 2001

        printable(bprm->buf[2]) &&
        printable(bprm->buf[3]))
     break; /* -ENOEXEC */
+printk("execmod:%s\n",bprm->filename);
    sprintf(modname, "binfmt-%04x", *(unsigned short *)(&bprm->buf[2]));
    request_module(modname);
 #endif

And I got:
#Mar  7 21:40:56 bcv66vbb kernel: execmod:/etc/X11/xinit.d/msec
#Mar  7 21:40:56 bcv66vbb modprobe: modprobe: Can't locate module binfmt-0000

Could this patch, or a better one, testing the result of request_module
be included in the kernel source. modprobe message have not enough information
