I think the problem depends on your configuration of nfss. Piet, I think you
used latex-nfss with oldlfont.sty loaded. In this case the problem does not
occur. If you try latex with basefont.tex (/usr/local/lib/tex/bin/amslatex
executable on your system, Piet), you will see you get italics. The problem
lies in how \rm is defined:

With basefont.tex only the \fontfamily is changed and \fontseries and
\fontshape (which determines normal, italic, slanted, etc.) are left
unchanged: 
	\def\prm{\fontfamily\rmdefault\selectfont}

With oldlfont.sty \fontseries end \fontshape are also changed (reset to
their default values):
	\def\prm{\fontfamily\rmdefault
	    \fontseries\default@series
	    \fontshape\default@shape\selectfont
	    \mathrm}

So to solve the problem, you either have to use oldlfont.sty (which you
probably don't want to use), or you have to replace \rm in your definition
by something else. Maybe someone else can comment on what is the best
solution.
