You can do it. You have to unmask the kernel_builtin USE flag to stop zfs
bringing in zfs_kmod, then unpack the sources and run the script to
install them into the kernel tree.
I run this script after emerging a new kernel
==================================================
#!/bin/sh
[[ -f /usr/src/linux/.config ]] || zcat /proc/config.gz
>/usr/src/linux/.config
SPL_EBUILD=$(ls -1 /var/portage/sys-kernel/spl/spl-0* | tail -n 1)
ZFS_EBUILD=$(ls -1 /var/portage/sys-fs/zfs/zfs-0* | tail -n 1)
SPL_DIR=$(ebuild $SPL_EBUILD clean prepare | awk '/Preparing source in/
{print $5}') ZFS_DIR=$(ebuild $ZFS_EBUILD clean prepare | awk '/Preparing
source in/ {print $5}')
cd $SPL_DIR
./configure --enable-linux-builtin --with-linux=/usr/src/linux
./copy-builtin /usr/src/linux
cd $ZFS_DIR
./configure --enable-linux-builtin --with-linux=/usr/src/linux
--with-spl=$SPL_DIR ./copy-builtin /usr/src/linux
==================================================
Then run make oldconfig and compile as usual.
