I think the 63 is a linux restriction...  not a restriction on logical 
partitions themselves.

This came from:

http://tldp.org/HOWTO/Partition/partition-types.html#logical


 One primary partition of a hard drive may be subpartitioned. These are 
logical partitions. This effectively allows us to skirt the historical four 
partition limitation.

The primary partition used to house the logical partitions is called an 
extended partition and it has its own file system type (0x05). Unlike primary 
partitions, logical partitions must be contiguous. Each logical partition 
contains a pointer to the next logical partition, which implies that the 
number of logical partitions is unlimited. However, linux imposes limits on 
the total number of any type of partition on a drive, so this effectively 
limits the number of logical partitions. This is at most 15 partitions total 
on an SCSI disk and 63 total on an IDE disk.
