I've had intermittent "freeze and reboot" and, worse, just plain freeze problems with the Core Duo's I've been testing.  I have not been able to narrow it down so I do not know if it is a platform issue or a CPU issue.  It appears to be HW, not SW, related since I have experienced the problem both under M$ and Linux 2.6 based OS's.  I have not tested the Core Duo's under *BSD.

Also, being that they are only 32b Core Duo's have limited utility for a present day DB server.

Power and space critical applications where 64b is not required may be a reasonable place for them... ...if the   
present reliability problems I'm seeing go away.
