 I am afraid this in a limitation in netcfg, with or without preseeding. 
 As far as I can see, autoconfiguration tries to automatically configure 
 both IPv4 and IPv6 and ignores static parameters; disabling it allows to 
 configure either IPv4 or IPv6 with static parameters, but not both. 
 There are no per-address family automatic/static configuration settings.
