So i built the kernel package from 2.6.32-13 like this as a regular user:
mkdir ~/src/linux
cd ~/src/linux
apt-get source linux-2.6/unstable
cd linux-2.6-2.6.32/
make -f debian/rules source
fakeroot make -f debian/rules.gen binary-arch_armel_none_kirkwood
Then i installed the resulting package as the superuser:
aptitude install initramfs-tools linux-base
dpkg --install linux-image-2.6.32-5-kirkwood_2.6.32-13_armel.deb
aptitude -f install
and generated a uBoot-friendly kernel and initramfs (thanks to Clint
Adams for helping me cargo-cult this):
cd /boot
mkimage -A arm -O linux -T kernel -C none -a 0x00008000 \
-e 0x00008000 -n Linux-2.6.32-2 -d vmlinuz-2.6.32-5-kirkwood uImage
mkimage -A arm -O linux -T ramdisk -C gzip -a 0x00000000 \
-e 0x00000000 -n initramfs -d initrd.img-2.6.32-5-kirkwood uInitrd
Then i stuck those on a local tftp server and tried booting it that way,
via the Marvell>> prompt for the bootloader:
setenv serverip 10.156.156.1
setenv ipaddr 10.156.156.34
tftpboot 0x8000000 guru/uInitrd
tftpboot 0x2000000 guru/uImage
bootm 0x2000000 0x8000000
and i get the following output:

So maybe the machine identifier in the guruplug patches is somehow
wrong, or doesn't account for the current system?
More notes on the way when i sort anything else out.
