I think you just need to modify the function pairs.default to something
like

function (x, labels, panel = points, main = NULL, font.main =
par("font.main"), 
    cex.main = par("cex.main"), cex.labels= par("cex"), ...) 
....
            text(mean(par("usr")[1:2]), mean(par("usr")[3:4]), 
                labels[i], cex=cex.labels)
....

I see S-PLUS computes the cex from the number if plots, and I suspect
we should consider a better default. pairs(USJudgeRatings[, 1:3])
looks pretty silly.

Well, all the font sizes have been altered since then, but with 0.99.0
imminent you might want to wait for that before upgrading.
