Can someone enlighten a new subscriber (and 4501 user) about this problem?
The mailing list doesn't seem to have a searchable archive.

I it simply that some boards had/have 33.333Mhz crystals that are 
significantly off frequency?

I do seem to be getting frequent re-synchronization messages from NTP as 
the system clock drifts on my recent (purchased october 2003) net4501,
but haven't fully investigated yet.
