And which package owns /lib/modules/2.6.30-ARCH/kernel/lib/zlib_inflate/zlib_inflate.ko?

$ zgrep -i ZLIB_INFLATE /proc/config.gz 
CONFIG_ZLIB_INFLATE=y

shows that ZLIB_INFLATE is not a module.
Did you left something from a previous (custom) kernel build?
A full depmod should be able to fix the problem.
