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