[gentoo-user] Loading, modules, via, /ec/conf.d/modules, minimalisticly

Hi,

I need to load some extra modules "manually" when
my Linux box boots to get access to an embedded 
system. These modules need to be added to 
/etc/conf.d/modules for various reasons.

The modules are:

ipt_MASQUERADE          1037  2 
nf_nat_masquerade_ipv4  1785  1 ipt_MASQUERADE
iptable_nat             1578  1 
nf_nat_ipv4             4811  1 iptable_nat
nf_nat                 11442  2 nf_nat_ipv4,nf_nat_masquerade_ipv4
nf_conntrack_ipv4      11964  1 
nf_defrag_ipv4          1395  1 nf_conntrack_ipv4
nf_conntrack           61998  4 nf_nat,nf_nat_ipv4,nf_nat_masquerade_ipv4,nf_conntrack_ipv4


How can I distinguish those modules from this list, which need 
to be listed in /etc/conf.d/modules from those, which get pulled in by
these?

Best regards
mcc
