Yes, the Linux kernel is limited. You'll find that other utilities
(e.g. bootloaders, BIOSes) also have their own limits.
To be really picky, the limit for IDE devices is actually 63 partitions,
and is an artificial limit mostly enforced by the major/minor device
numbering scheme. The 0th "partition" would be a block device that
represents the physical disk itself. Example below.
brw-rw---- 1 toor disk 3, 0 Mar 15 2002 /dev/hda
brw-rw---- 1 toor disk 3, 1 Mar 15 2002 /dev/hda1
brw-rw---- 1 toor disk 3, 2 Mar 15 2002 /dev/hda2
...
brw-rw---- 1 toor disk 3, 20 Mar 15 2002 /dev/hda20
...
brw-rw---- 1 toor disk 3, 63 Mar 15 2002 /dev/hda63
Similarly, the Linux kernel limits SCSI devices to 15 partitions.
