Yes. :)

MOL includes a small volume of drivers and such for OS X (and a similar
one for OS 9 and earlier). In the case of OS X, this collection includes:

* An ethernet driver
-and-
* A sound driver

...both packaged in a nice, neat .pkg.

Once you install it, a new ethernet device (on my system, it was called
"en1"; your title may vary) appears when you next open the Network
preference pane in System Preferences. From there on in, it should be
easy, so long as you know what you're getting into on the Linux side of
things... (see below)

Make sure your kernel has the following features compiled in and/or loaded
as modules:

* ip_tables
* ip_conntrack
* ipt_MASQUERADE
* iptable_filter
* iptable_net
* tun

Additionally, just in case, I loaded:

* ip_nat_ftp
* ipt_REDIRECT
* ipt_MIRROR

The complete output of my lsmod is below:

You will, once you set up the MOL Ethernet driver by installing the nifty
.pkg file included on the MOL volume :)

Mine only has one line that isn't a comment, or commented out:

netdev:         tun${session} -tun

I also edited /etc/mol/tunconfig and turned off PROVIDE_DHCP and
DNS_REDIRECT, and commented out NAMESERVER (I use a 'real' nameserver on
the Mac OS X virtualized-machine...

Hope the above helps.
