I guess you could try porting the OpenSolaris libumem to linux
and run SL or X while using it. We've found a heap of memory
allocation bugs using it. Or perhaps electric fence might be useful.

That would be almost of them. Btw, I still find it crazy
that even after so many years of hivemind knowledge about
how to do 64bit kernels and 32bit apps/libs, distro makers
apparently still don't seem to get it right. 

Why would you use 64bit? So firefox can crash harder and faster.
So your uber133t graphics card can mmap() its 1Gb of framebuffer.
To get access to extra registers. I'm sure there are other reasons.
