So, after switching to Gutsy, my X60s was going at about 12W.  I wasn't 
doing anything to ensure using less power though - wifi, all default 
modules were in (and I added ibm-acpi myself...).

I was having a little too much trouble with Gutsy though - wireless 
networking issues being the most significant.  If I had more free time I 
would have rolled with it and tried to fix it up.

So I went back to feisty, which claims 15W.  If I get a chance, I'll 
upgrade the kernel, but we'll see if I have the time for that....
