Dear Chris,

It happened, that recently I had to play with webMathematica
installation. For this purposes I had to run Mathematica frontend on Xvnc
without mentioned problems.  The complete solution in my case was to use
the following $fontpath line

$fontPath =
"/usr/X11R6/lib/X11/fonts/misc/,/usr/X11R6/lib/X11/fonts/Type1/,/usr/X11R6/lib/X11/fonts/75dpi/,/home/acus/bin/Wolfram/5.2/SystemFiles/Fonts/Type1,/home/acus/bin/Wolfram/5.2/SystemFiles/Fonts/BDF";


In adition I had to modify xstartup file in the ~/.vnc directory in the
following way

------------------------------xstartup---------------
#!/bin/sh

xrdb $HOME/.Xresources
exec /usr/X11R6/bin/fvwm 


----------------------
where .Xresources is the following file in my home dir:

----------------.Xresources----------------------MMA relevant
part--------

! please see also XMathematica.cde faile in instalation tree
XMathematica*fontList: -adobe-helvetica-bold-r-normal-*-17-*-*-*-*-*-*


! numlock
XMathematica*primaryModifierMask: Mod1Mask
XMathematica*secondaryModifierMask: Mod3Mask


! wrong behaviour!!
!XMathematica*geometry: 1580x1850


!*XMathematica.width: 1200
!*XMathematica.height: 1850

*useStandardColormaps: FALSE

*wwwBrowser: (URL=%s; (mozilla -remote "openURL($URL)" > /dev/null) ||
mozilla $URL) 


*printCommand: lpr -P WinEpson


---------------------------------------
With this modification Mathematica frontend starts correctly under Xvnc
(tightvnc tested) with correct fonts and no error warnings

 (well there one is printed in the console window: that 
-adobe-helvetica-bold-r-normal-*-17-*-*-*-*-*-* cannot be correctly
convereted to FontStruct. But this is irrelewant.
