Sure.

The "two amanda jobs" part is just having two configurations with two
disklists and running them in parallel:

    01      23      *       *       0-5     /home/amanda/bin/config0
    01      23      *       *       0-5     /home/amanda/bin/config1

The "two ethernet cards" part is a little trickier, and is a properly a
network administration question, not an Amanda question.  :-)

If:
    You have two routed subnets,
    
    The amanda server is dual-homed (i.e., has two hostnames),

    All DLEs in config0 are on subnet 0, all DLEs in config1 are
    on subnet 1,

...then it's trivial and just works.

If you're one big switched LAN, and your switches are VLAN-capable, and
you have control over the VLAN organization, you can do essentially the
same thing.

If you're one big switched LAN, and you can't do VLAN, then you try to
find out if your server and switch are capable of trunking.
