yes, dhcpcd and openresolv are designed for this.
You can use either the old style networking (net.eth0, net.lo, etc) in 
openrc-0.4.x (or 0.5.x with MKOLDNET=yes) or the new network script in 
openrc-0.5.0.

Caveats :)
dhcpcd-5 is designed to be run standalone, so don't configure any 
net.foo for dhcp. Infact, I'd go as far to disable dhcp entirely
modules="!dhcp" in /etc/conf.d/net

wpa_supplicant does not support interface hotplugging, so if you need to 
hotplug a wpa_supplicant driven interface you need to use net.eth0 and 
friends. I did submit patches upstream for this, but they were not accepted.

There is no PPP support in openrc-0.5.0 with the new network script - 
you'll have to start it yourself.
