When you have multiple figures, R tries to think for you and reduces the 
"base" size of text.  You can explicitly control this base size through 
par().  Does the following slight modification of your example do what 
you want?

test <- function(subfigure)
{
plot(c(1:10),c(1:10),cex=4)
text(1,9,subfigure,cex=10)
}
m <- matrix(c(1,2,5,5,3,4,5,5),4,2)
layout(m)
test("a")
test("b")
test("c")
test("d")
par(cex=1)
test("e")
