can also confirm that the GTS450 1GB is working out of the box with GraphicsEnabler=y
no freezes till now
still something wrong with this card.
system profiler shows card correct.
no freezes, no kp or something else.
but not usable for games or something else
WoW -> 6-8fps
cinebench 11 -> 4fps
cl info shows that the card is identified but shows Clock: 0 MHz
strange thing but i hope after final release this card will work proper
