Looks like I was too optimistic in my first estimation :) Still, testing 
  the fppkg project (commandline: "ppc386 fppkg.pp -Fulnet 
-FUunits/i386-linux") gives me approximately the same ratios as I 
initially got for xmlts:

               Patched                Unpatched
No smartlink
Build all   1,338,810,161          1,670,449,515
Load PPU      386,845,718            596,421,046

With smartlink
Build all   1,646,774,139          2,002,569,727
Load PPU      399,144,263            609,837,470

I guess these numbers are hardware-dependent in some way, so someone 
else may expect yet another values.
I'll try to do more research on this, and provide more 'small bits'... :)
