Maybe.  AFAIK multi-card has issues with current

A single card with two outputs (VGA + DVI or DVI + DVI) should work
just fine.

The single-card-two-monitors thing is easy, most of the time: plug in
the monitors, go to System -> Preferences -> Monitors and drag them
around the way you like.

There may be complications:

  * NVidia: if you use their proprietary driver, you must use their
    proprietary configuration application for stuff like this.  IIRC;
    I've avoided NVidia lately.

  * ATI 57xx series aren't supported at all by open drivers in Ubuntu
    10.04; you must either use VESA (which has no 3D acceleration and no
    multi-monitor support) or the ATI proprietary driver fglrx (but I
    don't know if it's supported at all with 10.04, or if it supports
    multiple monitors).

We don't really understand it, so we'll give it to the programmers.
