Hi Peter,
I got a little confused since you wrote something about Win2K8 32-bit so 
I didn't know whether you were referring to 32-bit guest or 64-bit one. 
The patch is necessary for x64 version of LSI SCSI drivers since it 
fixes the phase mismatch implementations. Linux doesn't have those 
issues since the jump registers 1 and 2 are the same. This was also true 
for 32-bit versions of Windows nevertheless Microsoft seems to change 
this to match specs in the x64 version of those LSI SCSI drivers. But 
it's great to hear it's working fine and this is not any other issue ;)

Regards,
Michal
