Indeed as far as I've understood, the whole virtual display is in the memory (i.e. it's the same than the frame buffer) and only a part of it lies on the real display at a given time. The hardware must then support dimensions for the frame buffer which are unusual for real displays. (Just making sure we're talking about the same thing. :))
All the XFree86 drivers I've used (i740, mga, nv, ati) have had some kind of limitations, probably related to hardware. Sometimes not much of the adapter memory is usable for the virtual display.
This comes from my own memory, so there (might) be errors:
adapter maximum driver memory virtual desktop size ------------------------------------------- nv (NV15?) 64 MiB 2048x2048 ati (Rad. VE) 64 MiB ~ 4096x2048 mga (G400) 32 MiB 16 MiB usable? i740 8 MiB 1600x1200?
