It's installed by the kernel image package: /boot/config-2.2.15
probably.

Did you try the 2.2.17 packaged kernels?

I'm wondering if there's a difference in config between the two you
tried... the installer does some skanky magic building them.  Here's
the difference between those two kernels:

# Fix .config for ramdisk rooting and kernel ip autoconfiguration.
# This image is >1440 KB and is suitable for CD/net booting.
sed 's:# CONFIG_CMDLINE_BOOL is not set:CONFIG_CMDLINE_BOOL=y \
CONFIG_CMDLINE="root=/dev/ram ip=off":' \
$builddir/usr/src/kernel-patches/powerpc/config.prep > .config.param

# Enable kernel ip autoconfiguration
sed 's:# CONFIG_IP_PNP is not set:CONFIG_IP_PNP=y \
CONFIG_IP_PNP_DHCP=y \
CONFIG_IP_PNP_BOOTP=y \
CONFIG_IP_PNP_RARP=y:' \
.config.param > .config.ipauto

# Enable nfsroot
sed 's:CONFIG_NFS_FS=y:CONFIG_NFS_FS=y \
CONFIG_ROOT_NFS=y:' \
.config.ipauto > .config


NFS root on, IP autoconfig on, and booting from a ramdisk.  one of
those is probably fixing your problem... i'd bet on the ramdisk.
