I think that is similar to crossfire, however you can mix and match any x1000 series cards. Although I think that if you had a x1800xt master card and a x1800xl then they both run at x1800xl speeds.
They don't they run at their seperate speeds, all you lose is 256mb Ram from the XT master, so you have an x1800 XT 256mb and an x1800 XL 256mb in Crossfire, you have to get the x1800 XT 512mb master card for the x1800 XL to run in Crossfire as they are not releasing an x1800 XL master, only downside to that is the higher price.
Don't go Crossfire on the x800/x850 series cards, their maximum resolution is 1600x1200, and they are stuck at 60hz.
The new RD580 motherboard Chipset is supposed to be out around Feb, Crossfire on that is much faster than the RD480 Chipset that is out now, and apparently is much faster than SLi, also rumour has it that the new Asus RD580 chipset board is due around the same time as the x1900, the 24th Jan.
Welcome to the forums btw.
