Just because it is absurd doesn't mean it wasn't built that way :)
I agree, and I'm trying to influence the next hardware design. However, what's already out there is memory units that must be accessed in 256MB blocks. If you want to remove/add a GB, that's really 4 blocks of memory you're manipulating, to the hardware. Those blocks have to be registered and recognized by the kernel for that to work.
