The 2TB size for msdos partitions is a problem independent of the 4k sector issue. Traditional 512 byte sector drives are now available in those sizes. It looks like we're going to have to move to a new partitioning label to solve this. There's actually another barrier at 8 or 16TB, which is where a 4k logical sector filesystem tops out using 32 bit block offsets (it's 8TB if the fs hasn't been proof checked against sign extension problems).
The limit for the MS-DOS partition tables is 2^32 sectors. The patch that Daniel posted was for a Linux kernel internal limit that set the limit to 2 TB.
