Cross-platform, human-readable, du on root partition that truly ignores other filesystems

I hate this so much:

Yet, I equally, if not quite a bit more, also hate this:

The people with the authority don't rotate logs or delete packages after install in my environment. Standards, remediation, cohesion...all fancy foreign words to me.
==============
How am I supposed to deal with / filesystem full issues across multiple platforms that have a devastating number of mounts?
On Red Hat el5, du -x apparently avoids traversal into other filesystems. While this may be so, it does not appear to do anything if run from the / directory.
On Solaris 10, the equivalent flag is du -d, which apparently packs no surprises, allowing Sun to uphold its legacy of inconvenience effortlessly.
(I'm hoping I've just been doing it wrong.)
I offer up for sacrifice my Frankenstein's monster. Tell me how ugly it is. Tell me I should download forbidden 3rd party software. Tell me I should perform unauthorized coreutils updates, piecemeal, across 2000 systems, with no single sign-on, no authorized keys, and no network update capability. Then, please help me make this bastard better:
pwd
/
du * | egrep -v "$(echo $(df | awk '{print $1 "\n" $5 "\n" $6}' | \
cut -d\/ -f2-5 | egrep -v "[0-9]|^$|Filesystem|Use|Available|Mounted|blocks|vol|swap")| \
sed 's/ /\|/g')" | egrep -v "proc|sys|media|selinux|dev|platform|system|tmp|tmpfs|mnt|kernel" | \
cut -d\/ -f1-2 | sort -k2 -k1,1nr | uniq -f1 | sort -k1,1n | cut -f2 | xargs du -shx | \
egrep "G|[5-9][0-9]M|[1-9][0-9][0-9]M"
My biggest failure and regret is that it still requires a single character edit for Solaris:
pwd
/
du * | egrep -v "$(echo $(df | awk '{print $1 "\n" $5 "\n" $6}' | \
cut -d\/ -f2-5 | egrep -v "[0-9]|^$|Filesystem|Use|Available|Mounted|blocks|vol|swap")| \
sed 's/ /\|/g')" | egrep -v "proc|sys|media|selinux|dev|platform|system|tmp|tmpfs|mnt|kernel" | \
cut -d\/ -f1-2 | sort -k2 -k1,1nr | uniq -f1 | sort -k1,1n | cut -f2 | xargs du -shd | \
egrep "G|[5-9][0-9]M|[1-9][0-9][0-9]M"
This will exclude all non / filesystems in a du search from the / directory by basically munging an egrepped df from a second pipe-delimited egrep regex subshell exclusion that is naturally further excluded upon by a third egrep in what I would like to refer to as "the whale." The munge-fest frantically escalates into some xargs du recycling where -x/-d is actually useful, and a final, gratuitous egrep spits out a list of directories that almost feels like an accomplishment:
Linux:
54M etc/gconf
61M opt/quest
77M opt
118M usr/ ##===\
149M etc
154M root
303M lib/modules
313M usr/java ##====\
331M lib
357M usr/lib64 ##=====\
433M usr/lib ##========\
1.1G usr/share ##=======\
3.2G usr/local ##========\
5.4G usr ##<=============Ascending order to parent
94M app/SIP ##<==\
94M app ##<=======Were reported as 7gb and then corrected by second du with -x.
Solaris:
63M etc
490M bb
570M root/cores.ric.20100415
1.7G oec/archive
1.1G root/packages
2.2G root
1.7G oec
Guess what? It's really slow.
Edit: Are there any bash one-liner heroes out there than can turn my bloated abomination into divine intervention, or at least something resembling gingerly copypasta?
