I have tried to typecast the HwFindAdapter like:
  (PHW_FIND_ADAPTER) HwInitializationData.HwFindAdapter = 
XenVbd_HwStorFindAdapter;

However this results in the following error and warnings:
  error C2220: warning treated as error - no 'object' file generated
  warning C4055: 'type cast' : from data pointer 'PVOID' to function pointer 
'PHW_FIND_ADAPTER'
  warning C4213: nonstandard extension used : cast on l-value

I might be doing something wrong, however my experience in C++ is limited.
