My Droid is stock 2.1, rooted with P3 1000 kernel. I have had the issues with stock kernel as well. Basically, some apps keep telling me I have insufficient space available when I try to update them. The main culprits are Shopper, Space Physics, and NESoid. Sometimes, uninstalling/reinstalling works, but the latest updates of Space Physics and Shopper keep telling me insufficient space. Settings, Memory says I have 91.54 MB of internal space left. Also, uninstalling and doing Titanium restores dont seem to work either...but just for those apps. Any ideas?
