This doesn't sound like a problem with specific bindings to me (never 
used suds though, only used ZSI as you can see in the samples in the 
SDK). From the symptoms you're using the wrong IMachine reference. On 
the other hand, I can't explain why setting the memory size with the 
same reference works, it's doing the exact same checks on the API 
implementation side.

Are you sure that the snapshot you are restoring is an "offline" one, 
i.e. for a powered off VM? Otherwise the VM is in saved state, which 
means no significant reconfiguration is possible (but again, same rules 
for HPET and memory size...).
