I do have root, but I need to reinstall adb since fixing my computer, unfortunately, I don't know if I can get you the "stock" /system filesystem, as I for some dumb reason decided to not back up before flashing LightningC, which is just a slimmed down optimized rom without the LG and Verizon bloatware. There is a clean base rom here on the forum, not sure if it's rooted or not, I could re-root, would that help if I flashed that? If you could PM me instructions and commands to get you what you need, I can zip it up and attach it as soon as I can!
Here's the clean rom I mentioned.

EDIT: Here is the output of /proc/mtd using "cat /proc/mtd" in a terminal emulator from the market, hoping that's what you were talking about.
Code:
dev: size erasesize name
mtd0: 00500000 00020000 "boot"
mtd1: 05000000 00020000 "cache"
mtd2: 00500000 00020000 "recovery"
mtd3: 00140000 00020000 "splash"
mtd4: 0bb00000 00020000 "system"
mtd5: 00080000 00020000 "fota_usd_mdm"
mtd6: 006a0000 00020000 "fota_sto_mdm"

mtd8: 00080000 00020000 "misc"
mtd9: 00180000 00020000 "persist"
And here is a zip file with the default.prop file and a tarball containing the /system filesystem!
