Peculiar. They're supposed to be roughly the width of a "0" in the
base font. The Postscript driver had a bug in the size calculations,
in that it subtracted 18 pixels from the radius, but that wouldn't
seem to be your problem if setting cex fixes things up.
What does par("cra") and par("csi") say on your respective systems?
(par("cra")/par("csi") should be the dpi of your device)

Yes, I believe we already have a bug report to that effect.
