my lsmod output is a superset of this list.

here's meminfo for my v440:

maybe it's the gcc/binutils? I'm using something older:

# gcc --version
gcc (Debian 4.6.3-14) 4.6.3
Copyright (C) 2011 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.  There is NO
warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

My binutils is 2.22-8+deb7u2

the other difference is that (due to firewall/proxy headaches) I 
git-pull on a different machine and then rsync over that tree to
the v440. 

I did not see anything significantly different about the ps/interrupts
etc. I do not have irqbalance or ntpd on the v440, though.
