geometry.cfg from tex/xelatex/ is found because there is no  
geometry.cfg otherwise in TeXLive-2007. After not finding anything in  
tex/latex/, the whole of tex/ is searched which leads finally to tex/ 
xelatex/.

Try for example "kpsewhich --show-path=.tex --progname=pdflatex" to  
see in which order directories are searched. Here on the Mac I get  
(with minor editing):

$ kpsewhich --show-path=.tex --progname=pdflatex | tr : '\n'
.

~/.texlive2007/texmf-var/tex/latex//
~/Library/texmf/tex/latex//

!!/usr/local/texlive/2007/texmf-dist/tex///

implying that tex/latex is searched first, then tex/generic/, then  
tex/. This corresponds to the setting, in texmf.cnf:

TEXINPUTS.pdflatex      = .;$TEXMF/tex/{latex,generic,}//
