Problem requesting IRQ with 2.4.2 kernel

Hi !
I'm using a clone of the bk tree to compile a 2.4.2 kernel.
I have also downloaded the code from Gabriel Paubert for the
pci2vme chip from TUNDRA.
Before with a 2.4.0 kernel I succesfully inmod the code.
But know I have the following error :
Unable to grab interrupt 16 for VME !
Trying to free free IRQ16
And if I have a look at /proc/pci I have the following :
PCI devices found:
Bus 0, device 0, function 0:
Host bridge: Motorola Raven (rev 5).
IRQ 16.
I/O at 0x0 [0xffffffff].
Non-prefetchable 32 bit memory at 0xfc000000 [0xfc03ffff].
Bus 0, device 11, function 0:
ISA bridge: Symphony Labs W83C553 (rev 16).
IRQ 16.
Bus 0, device 11, function 1:
IDE interface: Symphony Labs SL82c105 (rev 5).
IRQ 16.
Master Capable. No bursts. Min Gnt=2.Max Lat=40.
I/O at 0xffffff0 [0xffffff7].
I/O at 0xfffffec [0xfffffef].
I/O at 0xfffffe0 [0xfffffe7].
I/O at 0xfffffdc [0xfffffdf].
I/O at 0xfffffc0 [0xfffffcf].
I/O at 0xfffffb0 [0xfffffbf].
Bus 0, device 13, function 0:
Bridge: Tundra Semiconductor Corp. CA91C042 [Universe]
(rev1).
IRQ 16.
Master Capable. No bursts. Min Gnt=3.
Non-prefetchable 32 bit memory at 0xeffef000 [0xeffeffff].
I/O at 0xfffe000 [0xfffefff].
How can avoid all this pci board to have the same IRQ ?
Is this an openPic related problem ?
