I have a Linksys NSLU2, here's the memory:

-bash-3.2$ free
              total       used       free     shared    buffers     cached
Mem:         30520      29828        692          0       8616       7288
-/+ buffers/cache:      13924      16596
Swap:       112440      13844      98596

32MB RAM in the device. It has a hard time compiling the prerequisites 
for tahoe. Plus it's an ARM processor, so it didn't work right.
