I recently posted to this list regarding a discrepancy in the version 
my X server reported.  I'm running NetBSD 3.0, which should have 
XFree86 version 4.5.0.  However, xdm's log gave NetBSD 1.5.2 with 
XFree86 3.x.  A responder to that e-mail (thanks to Mark Par) suggested 
checking XFree86 -version.  I poked a bit further, and got the 
following (notice that X and XFree86 give different results):

Any thoughts as to what might be going on?
