Comment 8 for bug 722185

Okay, I just built the kernel source from the linux-source-2.6.38 package using config-2.6.38-7-generic from the linux-image-2.6.38-7-generic, only changing CONFIG_VERSION_SIGNATURE, booted the new kernel, and the wireless connected successfully, so I am stumped.

What could be the difference between the linux-image-2.6.38-7-generic package and building a kernel with the config from that package and the linux-source-2.6.38 package using:
make
make modules_install
cp .config /boot/config-2.6.38-jconti-09
cp System.map /boot/System.map-2.6.38-jconti-09
cp arch/x86/boot/bzImage /boot/vmlinuz-2.6.38-jconti-09
update-initramfs -k 2.6.38-jconti-09 -c

then booting the vmlinuz-2.6.38-jconti-09 kernel and initrd.img-2.6.38-jconti-09?
