Well, I finally get evidence that my mainboard is a "K7N2 Delta-ILSR"
not a "K7N2 Delta-L" (from the shipping package, the invoice, and online
review of the two motherboards). So the BIOS version 7.4 is a valid one.
I updated the BIOS to the version 7.8. Now the drift is low and ntpd
happy (me too), all that without the "noapic" option.
Strange is that the kernel log is almost the same but this little
difference:

The following message is still here:

But all work fine with the latest BIOS.
For me the issue is solved. A lot of thanks to all peoples that helped
to this thread with special mention for John Stultz. I hope that the
others that have the same problem can solve it the same way.
Just to show how well is the 2.6.14 with the latest BIOS, here is the
drift according to the John Stultz python script:

It's very very low, far more that with 2.6.9 kernel and old BIOS. MSI
have obviousely fixed a timer issus in the BIOS, but this is not show in
the BIOS history.
