Thanks for the response and the tip. I was able to get it to work using
the following command:
fakeroot make-kpkg --initrd --revision=rt2x00 --arch=powerpc
I used buildroot to build the cross compiler toolchain. I was going to
use emdebian but they did not have a working set for powerpc arch.
Note that above I compiled the rt2x00 kernel branch since I needed to
use the driver. However, this should work with any kernel.
And as a final step, I had to generate the initrd image manually and
set up the symbolic links for initrd and vmlinux to point to the build
The initrd image was built using the following command:
update-initramfs -c -k 2.6.30-rc6-wl
Hope this helps somebody.
