> \font\tenbi="Trebuchet MS Bold Italic" at 10pt

OK, I've finally solved the problem by going a bit further in the 
redefinitions:

	\input lcdplain

	\font\tenrm="Trebuchet MS" at 10pt
	\font\tenit="Trebuchet MS Italic" at 10pt
	\font\tenbf="Trebuchet MS Bold" at 10pt
	\font\tenbi="Trebuchet MS Bold Italic" at 10pt

	\font\sevenrm="Trebuchet MS" at 7pt
	\font\sevenit="Trebuchet MS Italic" at 7pt
	\font\sevenbf="Trebuchet MS Bold" at 7pt
	\font\sevenbi="Trebuchet MS Bold Italic" at 7pt

	\font\fiverm="Trebuchet MS" at 5pt
	\font\fiveit="Trebuchet MS Italic" at 5pt
	\font\fivebf="Trebuchet MS Bold" at 5pt
	\font\fivebi="Trebuchet MS Bold Italic" at 5pt

	\textfont0=\tenrm \scriptfont0=\sevenrm \scriptscriptfont0=\fiverm
	\def\rm{\fam0\tenrm}
	\newfam\itfam \def\it{\fam\itfam\tenit}
	\textfont\itfam=\tenit \scriptfont\itfam=\sevenit 
\scriptscriptfont\itfam=\fiveit
	\newfam\bffam \def\bf{\fam\bffam\tenbf}
	\textfont\bffam=\tenbf \scriptfont\bffam=\sevenbf 
\scriptscriptfont\bffam=\fivebf
	\newfam\bifam \def\bi{\fam\bifam\tenbi}
	\textfont\bffam=\tenbf \scriptfont\bifam=\sevenbi 
\scriptscriptfont\bifam=\fivebi

	\rm

i.e. by redefining \rm \it etc. *after* loading the Trebuchet fonts.

With that the output of "${\rm e}^{-{\rm i}\sigma t}$ and $e^{-i\sigma 
t}$" looks, typographically speaking, a bit strange (mixture of serif 
and sans-serif in maths), but at least it's correct TeX-wise:

Now I'll be looking for a LaTeX equivalent of the above!
