Boot - Cannot find map file

Hello,

i686-pc-linux-gnu, (B)LFS 2.6.28.2

Absolutely by happenstance, I noticed these first lines
in 'kern.log' file on any system boot:

... kernel: klogd 1.4.1, log source = /proc/kmsg started.
... kernel: Inspecting /boot/System.map
... kernel: Cannot find map file.
... kernel: No module symbols loaded - kernel modules not enabled.
... kernel: BIOS EBDA/lowmem at: 0009ec00/0009ec00
... kernel: Linux version 2.6.28.2 (root at AlexLFS)
            (gcc version 4.1.2) #1 SMP PREEMPT
            Thu Jan 29 21:22:12 gst 2009
... kernel: KERNEL supported cpus:
    ...

In one form or another this unsettling message (lines 3,4) may
have existed since the beginning of time (i.e. not only at
2.6.28.2) - who knows.
I always peruse the console boot display pretty carefully and I
don't remember ever seeing anything untoward in this respect.

'System.map' is always properly set in '/boot' as a symlink to
the actual 'System.map-...' file (also in '/boot'; currently at
754232 bytes - mileage may vary, obviously).
Correct permissions and ownership.
System works A-OK.

Has anybody seen such a thing before?
Thanks,
-- Alex
