Sundar,

Thank you very much.  I see my mistake.  Much appreciated.

Because you're not calling trellis.par.set correctly. It should be:

trellis.par.set(par.ylab.text = list(cex = 0.65), par.xlab.text =
list(cex = 0.65))

However, I usually do things like this:

my.theme <- list(par.ylab.text = list(cex = 0.65), par.xlab.text =
list(cex = 0.65))
barchart(..., par.settings = my.theme)

so the settings are only changed for the current plot and not globally.

HTH,
