I use two with no problem on 4.4-STABLE:

atapci1: <Promise TX2 ATA100 controller> port 0xff60-0xff6f,0xff88-0xff8b,0xff80-0xff87,0xff8c-0xff8f,0xffa0-0xffa7 mem 0xffbe4000-0xffbe7fff irq 5 at device 17.0 on pci0
ata2: at 0xffa0 on atapci1
ata3: at 0xff80 on atapci1
atapci2: <Promise TX2 ATA100 controller> port 0xff90-0xff9f,0xffe0-0xffe3,0xffa8-0xffaf,0xffe4-0xffe7,0xfff0-0xfff7 mem 0xffbec000-0xffbeffff irq 11 at device 19.0 on pci0
ata4: at 0xfff0 on atapci2
ata5: at 0xffa8 on atapci2
ad4: 19092MB <ST320413A> [38792/16/63] at ata2-master UDMA100
ad6: 19092MB <ST320413A> [38792/16/63] at ata3-master UDMA100
ad8: 19092MB <ST320413A> [38792/16/63] at ata4-master UDMA100
... etc etc ...

I don't know why they are saying they don't support two in a machine -- the
on-card BIOS is even nice enough to only run once and it shows all eight
possible devices in the same screen together! :)  Never tried 3, though.

I don't remember seeing anything in the manual about multiple controllers. 
Maybe that's just something their tech support people say...

I have also had success using multiple SIIG-brand ATA controllers.  Despite
previous bad experiences with some of their (admittedly the cheapest in the
store :) hardware, I've had good luck with their IDE stuff. I don't
remember exactly which chip it uses; the machine I have them in is at home
and powered off at the moment.  YMMV.
