yes. It connects to subsystems 1 and 2. In general, all CSR calls made 
by kernel32.dll are easily identifiable as calls to either subsystem 
from their code (the subsystem code is in the upper 16 bits). The GUI 
subsystem's functions, if you were wondering, are:

SrvExitWindowsEx
SrvEndTask
SrvLogon
SrvRegisterServicesProcess
SrvActivateDebugger
SrvGetThreadConsoleDesktop
SrvDeviceEvent
SrvRegisterLogonProcess
SrvCreateSystemThreads
SrvRecordShutdownReason

1=base and 2=console, as Alex reported. There are two missing servers: 
0=csr and 3=user. Maybe 3 is connected to by user32.dll or gdi32.dll and 
0 is a default gate. Mumble...

Hmm... where are these symbols from?

0 is csrsrv.dll, and it's used by the other servers (ie, base and 
console connect to server 0 (but they use server-to-server calls which 
are much faster, see my ntdll/csr changes that you have)). 3 is 
winsrv.dll and it's what user32.dll connects to. winsrv handles all 
sorts of misc stuff (like exitwindowsex) and also has some connections 
with win32k.sys. After commiting csr I'll probably work on 3 inside 
winsrv, since it's easier to implement then basesrv.dll (which is huge, 
since it handles all SxS stuff too now).

winsrv.dll.

Oh, and I made a slight mistake, i said that the Console Server was 
inside basesrv.dll, it's not. It's inside winsrv.dll, my apologies.
Here are the functions, for information:

@8 of course since they are all CSR APIs (IN PCSR_API_MESSAGE, OUT ULONG 
Result)

And, as KJK stated, the APIs for Server 3 are:

SrvExitWindowsEx
SrvEndTask
SrvLogon
SrvRegisterServicesProcess
SrvActivateDebugger
SrvGetThreadConsoleDesktop
SrvDeviceEvent
SrvRegisterLogonProcess
SrvCreateSystemThreads
SrvRecordShutdownReason

(Note that winsrv handles WM_DEVICE event or changed APIs, with 
SrvDeviceEvent)

Oh, and before I forget, basesrv is also largely responsible for VDM.
