Does this patch still work for SP3?

Because my current VIDEOPRT.SYS has 120 exports, nor just 115:

start of file lnk.c:


#pragma comment(linker,"/export:...=vidprt0.VideoPortInterlockedDecrement,@1")
#pragma comment(linker,"/export:...=vidprt0.VideoPortInterlockedExchange,@2")
#pragma comment(linker,"/export:...=vidprt0.VideoPortInterlockedIncrement,@3")
#pragma comment(linker,"/export:...=vidprt0.VideoPortAcquireDeviceLock,@4")
#pragma comment(linker,"/export:...=vidprt0.VideoPortAcquireSpinLock,@5")


exports of current VIDEOPRT.SYS:


101A8     1       12AE VideoPortInterlockedDecrement
101AC     2       1296 VideoPortInterlockedExchange
101B0     3       12A0 VideoPortInterlockedIncrement
101B4     4       18E6 PortNotification
101B8     5       901E VideoPortAcquireDeviceLock


As you can see, there has been a new export inserted at #4.
