Yes, and also on EISA (although you have to specify level trigerred).

I probably wasn't clear enough in my original post, so I'll explain the
hardware setup - its a dual P133 (neptune) mobo, 128MB ram, with EISA and
PCI slots. NOTE: there is no onboard floppy or ata! There no onboard
serial or parallel ports. There is no onboard video.
Its got a macronix net card (irq 10), an Adaptec scsi card (irq 15), and
the Promise IDE card (irq 14) in the PCI slots.
Its got an Adaptec scsi card (irq 11) and a video card in the EISA slots.
The floppy controller is enabled (irq 6) on the Adaptec card.
The problem is that the ata driver insists that there are controllers at
ata0 and ata1 using irq 14 & 15 even though this is false.
Also note that the ata driver insists on owning the irqs:
# vmstat -i
interrupt total rate
stray irq7 1 0
ahc0 irq11 14 0
dc0 irq10 26105 0
ata0 irq14 189875 0 <-- should be atapci0
ata1 irq15 8902 0 <-- should be ahc1
atkbd0 irq1 2 0
fdc0 irq6 4 0
clk irq0 52368568 99
rtc irq8 67034815 128
Total 119628286 228
And just for the record, here is a pciconf -lv :
