NFS server

Anyone got NFS server to run? I need something very lightweight and I dont want to run samba. Unfortunately:

zcat /proc/config.gz | grep NFS
# CONFIG_USB_FUNCTIONFS is not set
CONFIG_NFS_FS=y
CONFIG_NFS_V2=y
CONFIG_NFS_V3=y
# CONFIG_NFS_V3_ACL is not set
# CONFIG_NFS_V4 is not set
# CONFIG_NFS_SWAP is not set
CONFIG_ROOT_NFS=y
# CONFIG_NFSD is not set
CONFIG_NFS_COMMON=y

Is it possible to recompile kernel for this board?

The rel-19 page lists kernel source as a separate package:

I would assume you can download and cross compile it as any other ARM kernel.
