While not The Right Thing (TM), here's what I did in case someone else
finds it useful:

# First, use 'set table' to get the proper kdens curve fit
set samples 1000
set table 'random.kdens'
plot "random.tmp" using 1:(1.0/nsamp) title 'Logscale x' smooth kdensity
unset table

# Second, plot the curve fit on a logscale
set output "logscale.ps"
set logscale x
plot "random.kdens" title 'Logscale x' smooth kdensity with lines

Please give a shout if there's something cleaner/prettier/simpler,
