My experience (with X 10.0.4 and X 10.1) is that it is much faster with 
the new revision. Considering what I know about Linux (not much, but I 
have installed and run it on PPC) and how my machine is configured, I 
suspect it is the Swap file slowing things down for you.
On my G4 with 192MB of RAM under Linux, the swap files were rarely, if 
ever accessed. Linux has much less hardware requirements than OSX (or 
Windows, for that matter) so the actual point where swap is used less 
may need 256 or some other configuration under OS X.
Since I have added 2 512MB sticks to my stock 128MB G4, I suspect the OS 
doesn't need swap as much as it might in a more restrictive RAM 
configuration. I never did run the machine with the stock RAM alone (I 
bought 133 RAM for my G4/400 and brought it over to my new QuickSiver) 
so I don't have any specific history to help figure out if that's really 
it.
All flavors of UNIX use swap; there are some OS X users (check out 
macfixit or macupdate) who create dedicated swap partitions.
