I believe it would only require a capable motherboard and power supply, and a crossfire bridge (the band that connects them 2).
 
One of them needs to be the x1900xt Crossfire Edition card (aka a Master Card). You also need the crossfire DVI dongle that comes with the card. Basically, back in the day whe Crossfire first came out you needed a Master Card + a regular card OR (2) Master Cards. They used a dongle that plugged into the DVI out on one card and a special connector on the master card.

The cards now ALL have Crossfire built in and use a Crossfire bridge. Back in the day with the x1900's, you needed special cards. BLAH!, i know I had an x1900xtx and wanted to do this but the master cards were expensive and hard to find.

Looks like this.

So if i brought a new ATI Radeon Graphic off the shelf i could connect it up with one or both of my X1900 XT(s). Would that link them all up together??
 
No, you can only use a x1900 Crossfire Edition card an a x1900XT,x1900XTX, x1900 CF Edition card together. I also believe you can use the x1950 cards.

If you got a new ATI card you may as well not even use the x1900xt cards. They have to be of the same series to crossfire.
