Custom Firmware supporting NFS
For all WL-HDD users here's a custom firmware which includes:
 * telnet daemon
 * nfsv3 daemon
 * vsftpd daemon (replaces stupid-ftpd)
 * samba 3.0.9 (supports CIFS)
 * doesn't poll for the harddisk each 5 seconds

Every feature of the original 1.1.2.8 firmware is in this custom version, also NTFS R/W support
