There are no options you can reach, if you don't enable CONFIG_EMBEDDED.
The network stack itself depends on netlink, so you usually can't switch
that off too.

Well, I have networking just fine.. maybe you can suggest why I keep
getting these errors then?

Ick, no idea how this can happen.
What does:
cat /proc/net/netlink
print? It has a line like this, when the daemon is listening:
sk Eth Pid Groups Rmem Wmem Dump Locks
f257a800 15 16733 ffffffff 0 0 00000000 2
What does:
strace -s1000 -t udevmonitor
print? It looks like this, if it works:
socket(PF_NETLINK, SOCK_DGRAM, 15) = 4
bind(4, {sa_family¯_NETLINK, pid\x16739, groupsÿffffff}, 12) = 0

Hello,
is is possible to prevent _some_ modules to be loaded at boot time while
allowing them to be loaded later?
I know about /etc/modprobe.d/blacklist but listing a module there prevent
aliases expansion.
E.g. I want ipw2200 module not to be loaded at system boot, but I want this
module to be loaded if I do ifconfig eth1 up. Is this possible?
