Separate X consoles one after another grab PCI resources. 2nd, 3rd ... X
server don not know about another X, which already use specific PCI resources.
Run or run not 2 X consoles is very hardware depended.
However Nvidia binary drivers are stable. One enthusiast of multiseat send
PC hardware to Nvidia developer's headquarters and as result Nvidia binary
drivers became stable since 2004 - 2005, i could not recall. Nowadays Nvidia
driver is stable but have side effect - when X neighbour logout , running
X may show blank, black screen up to 0.5 seconds. Looks like all additional
video adapters doe restart, no matter is that necessary or not necessary from
view point of end user.
