When did you remove Google Updater? I read the four most recent minidumps from today (5/6/09) and all four errors are 0x1A. They only cite a Windows OS driver which is too general to be of much help.
However, in the cited Process part of the minidump all four note Googleupdater.exe. If you have uninstalled this software but the executible is still present then it very well might be one of your issues causing your BSODs.
