Yes, it works absolutely fine. Have been moving around 35GB files, and 
have been running a big postgres database on it (and inserting the 35GB 
sql dump into it).

I think there were three options for the memory hole, one said hardware, 
the other said software and can't remember the third one. Setting it to 
software made the 4GB available and have had no problems whatsoever. 
This is using the latest debian stock kernel (2.6.11-9-amd64-k8-smp).
