I'm running FreeBSD on a range of PCs, from
Pentium-1 (60 MHz) to Pentium-4 (2.60GHz), though
none but one has a 'ata2' line in the dmesg
output:
ata0: channel #0 on atapci0
ata1: channel #1 on atapci0
...
ata2: <Generic ESDI/IDE/ATA controller> at port
    0x36e-0x36f,0x168-0x16f irq 10 on isa0
ad0: 6149MB <QUANTUM FIREBALL EX6.4A/A0A.0D00>
   [13328/15/63] at ata0-master UDMA33
ad1: 4892MB <QUANTUM FIREBALL EL5.1A/A08.1100>
   [10602/15/63] at ata0-slave UDMA33
acd0: CDROM <GCR-8521B/1.02> at ata1-master PIO4
What is so special about this particular PC, that
it has an ata2, unlike all other PCs I have?
Can I add more than 4 disks (2 masters + 2
slaves)
to this PC? Or is this ata2 for something else?
         

You have more than 2 controllers.  A whole dmesg
would help, or just tell us your make/model of
your motherboard.
   

Don't know the details of my motherboard.
Whole dmesg output is here:

So you have an intel 440bx chipset.  From what I see at intel's site 
there is just the standard ide controller on the chipset.  Ata 0 and 1 
are intel for sure, and like some one else said the ata2 is likely an 
add in card or an extra chip on your motherboard.
