I did some work a while back to get GPLPV working with larger disks. That was 
to fix a problem with 2TB disks though (512 * 2^32 bytes) as once you get 
larger than a 32 bit block address you need to go to 64 bit block addresses 
which is a different set of scsi commands.

That was a while ago though and it's possible that bitrot has crept in... I'll 
test with a 4TB (or something like that) sparse file and see what happens.

Can you confirm that a PV Linux domain has no such problems?
