Thanks Daniel, I think my gentoo NIC is OK (I haven't noticed such problems 
when I connect with my gentoo to other servers).  Getting 1 Mbps upload at 
this time of my local ADSL availability remains wishful thinking.  At best I 
see around 407 kbps average, and when throttled this drops to 150-200 kbps.  
What would be a good speed to limit uploading to, given that I would rather 
complete the upload sooner rather than later.

I have tried both md5sum and sha1sum with similarly unreliable results.  I'll 
try speed limiting next and see what gives.
