The procedure you describe above was executed in this case; the conf file 
in the original message was generated by 'Xorg -configure', and the log 
file was generated by 'Xorg -conf /root/xorg.conf.new'.  Additionally, the 
same release of xorg is running successfully on three of my 12 machines - 
the others run x clients only (in the case of the headless boxes), or (in 
two cases) are still running 4.10 with XFree86. This problem appears to be 
specific to the particular hardware configuration described in my initial 
note. (By way of explanation, the machine in question had run W2K until 
last week, but I decided to upgrade it to FreeBSD 5.3 for better 
reliability and improved function.) I have searched the X.org archives 
(and even resorted to google) for config information specific to the 
display called out above - with null result.

See above. Perhaps a detailed look at the log file will reveal to you a 
clue which I have overlooked.  I've not yet tried an explcit 'modeline' 
config - but my interpretation of the log from a subsequent run with the 
explicit monitor parms generated by -configure (but commented out in the 
auto-generated config) uncommented seems to indicate that the 
initialization process is failing to read the "Monitor" block, or the 
values are being overridden.

Any substantive notions will be welcome.
