Biztalk 2006 (not r2) - original soap fault capturing

Question

Hi,
I'm working on BizTalk 2006 (NOT R2) and using the old Soap Adapter. Is there a way I can get hold of the original soap fault that was received by the adapter rather than the one that the adapter itself generates (where it adds NACK) to the response?
Thanks,

Let me explain ...
This is what end system web service returns as a fault ...
<NS1:Envelope xmlns:NS1="http://schemas.xmlsoap.org/soap/envelope/">
<NS1:Body>
<NS1:Fault>
<faultcode>NS1:Server</faultcode>
<faultstring>User generated exception: xyz </faultstring>
<faultactor/>
<detail>
<ErrorSummary>
<ErrorCode>EC0001</ErrorCode>
<ErrorMsg>Unknown system error.</ErrorMsg>
<ErrorSystem>SomeSystemName</ErrorSystem>
</ErrorSummary>
</detail>
</NS1:Fault>
</NS1:Body>
</NS1:Envelope>
This is what SOAP Adapter converts it to by default:
<SOAP:Envelope xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/" SOAP:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
<SOAP:Body>
<SOAP:Fault>
<faultcode>Microsoft BizTalk Server Negative Acknowledgment </faultcode>
<faultstring>An error occurred while processing the message, refer to the details section for more information </faultstring>
<faultactor>http://somewebserviceurl</faultactor>
<detail>
<ns0:NACK Type="NACK" xmlns:ns0="http://schema.microsoft.com/BizTalk/2003/NACKMessage.xsd">
<NAckID>{0381BF90-CFCC-403C-BB61-9B0D831F7CB9}</NAckID>
<ErrorCode>0xc0c01f07</ErrorCode>
<ErrorCategory>0</ErrorCategory>
<ErrorDescription>SoapException: User generated exception: xyz</ErrorDescription>
</ns0:NACK>
</detail>
</SOAP:Fault>
</SOAP:Body>
</SOAP:Envelope>
Now when you create a catch exception block with a SoapException object, what you'll get basically is the Fault after it is converted by SOAP Adapter. What gets logged to the event log as error text is the text contained in ErrorDescription node of NACK.
What I want to access is <detail> section of the original fault message.
