I'm not able to create Volume groups successfully on a Big Endian Xscale
Intel IXP425; Here is a log of what happens, along with some
potentially helpful debug...
dd if=/dev/zero of=/dev/discs/disc0/disc bs=1M count=1

I'm using glibc-2.3.2 and a gcc 3.4.0 FYI.
Also, I read the LVM2 is not focusing on performance and may be
extremely slow compared to LVM1 (factor or 2 was thrown around); Is
this still true? I need max speed from my disk subsystem, as I'm
already on a slow platform. I tried using LVM1, but the compile is
massively broken, and it looks like modern 2.6 kernels don't support
this (No def of LVM_MAJOR, etc, etc); Perhaps I just need to dig some
more into making LVM1 work for me.
