did you configure manually your ip for testing before starting net.eth0 ???
in this case, try

ifconfig eth0 down

and /etc/init.d/net.eth0

if work fine, just add it to default profile

rc-update add net.eth0 default

just an explanation:

ifconfig do up on network card, so net.eth0 try up too and fail cause
already up
they don't try down before up ... so

if you configure manually by typing command
ifconfig eth0 MYIP netmask MYNETMASK brd MYBRD
route add default gw MYGW

so .. eth0 is up and net.eth0 couldn't do up again
so ifconfig eth0 down shutdown the network card, and so all work fine after
:)

have fun
