:-)
probably not unless you want also to use  multiple framebuffer
consoles( in case your card is supported by rivafb driver )
but i think this won't be possible with this card without adding additional
one

right, it looks so,
but i'm tottaly puzled why it doesn't lock up completely
to the kernel/ Xfree it's a single card
both XFree instancies are talcking to the same memmory,
to the same device check your XFree logs, it's a single device, with single
bus id,
with the same memmory size /* your card doesn't have 256Mb memory, does it
*/
( i assume also same registers and memmory addresses)

i really doubt it will work with only one card of this type,
and i totally don't understand why it doesn't freeze

it must work or freeze 
/* that's the problem with this aproach, on some combinations

 */

it must be that the nvidia driver is doing some  deep dark magic.
the only one that can give some info on the problem is Nvidia support team,
(and i'm not sure they'll be willing to :( )

not sure about that :(

it's probably not X but the nvidia driver itself, and i really doubt 
someone ( except Nvidia )  can hack it

sorry, but i really think you'll need an aditional card :(

the prefbusid needs a diffenerent BusID, in your case with a single BusID
it can not accompilsh anything

BusID is an standard XFree Option to be used with Xinerama

PrefBusID is a hack, which tells XFree to use the card with specified
BusID, and to ignore (not to disable) other present graphic cards
