Well, but indeed the OP is right: there's a severe problem at
least in some cases, including my own (Linux, Fedora 13)
*iff* "ComputerModern" is used.
I'm too time-squeezed currently to give much more details

the "ComputerModern" family or outside R in the font (metric?)
files used or possibly even the postscript viewer (but I doubt
the last one).
