This has nothing to do with only having 1GB of kernel address
space and not enough virtual space to load a large swath of drivers
or support modules loading reentrantly. It's a little difficult to quantify
how much kernel address space will be needed when you don't
know if a full configuration will fit into it. The fact people use this
patch at all is **EVIDENCE THAT THERE ALREADY IS A PROBLEM**
with limiting kernel address space to 1GB. And who the hell cares about
a mouldy, antiquated ABI spec modeled after 1970 Unix technology anyway? It
should be another option for executable formats. All this ABI compatibility huey
is some Intel/SCO pipe dream for supporting applications across multiple Unix
platforms anyway. If it doesn't run on Linux, who the hell cares?
