ATI <http://www.ati.com> has several dual head video cards ...

Radeon 9600, Radeon 9500 PRO, Radeon 9200, Radeon 9000 PRO,
Radeon 8500, Radeon 7500, Radeon 7000, Radeon 7000 IGP,
and Radeon VE.

Dual cards are nice, but only have one LUT, which means you
can only color-manage one of the outputs.  Having separate
cards is cheaper and more flexible, and you may be able
to keep your existing card.  I have 3 x Matrox G200 cards
and each one can be color-managed and calibrated individually
for each monitor.

If the two monitors will be side by side, you will want to
be sure that both monitors have built-in magnetic shields.

I've heard of magnetically shielded speakers, but monitors
with built-in magnetic shields???  I've never seen such a
thing listed in any manufacturer's feature lists.  My 3 monitors
are sited almost touching each other, but there is no disturbance
other than when switching on or degaussing one of them - then
they all get degaussed.  ;-)
