kernel object sizes

Hi,
I have compiled the new 2.6.30, and to my surprise every single object is significantly bigger than it was just in 2.6.29.

ls -lh Desktop/Linux-src/linux-2.6.30/arch/s390/boot/image
-rwxr-xr-x 1 user user 6.6M 2009-06-12 10:49 Desktop/Linux-src/linux-2.6.30/arch/s390/boot/image
ls -lh Desktop/Linux-src/linux-2.6.29/arch/s390/boot/image
-rwxr-xr-x 1 user user 4.5M 2009-06-12 10:33 Desktop/Linux-src/linux-2.6.29/arch/s390/boot/image

Same compiler, same machine, same everything.
Configuration wad copied over from 2.6.29, completed by suggested defaults. could find no entry that might produce this overhead (additional debug info, symbols, etc.).
Any ideas?
