Xorg 7.2 doesn't scan second PCI bus

[Laurent Lagrange]

Hi

I'm working on a powerpc platform with 2 PCI busses. I'm writing a driver
for a video card and I used to test it with Xorg 6.8.2. I decided to go on
to Xorg 7.2 so I cross built it. My problem is that Xorg doesn't find my
video card, because it doesn't scan the second pci bus where the card
resides.

Here my log :

...

And if I check with scanpci :

# scanpci

pci bus 0x0000 cardnum 0x01 function 0x00: vendor 0x10e3 device 0x0148
 Tundra Semiconductor Corp. Tsi148 [Tempe]

Did I make a mistake when cross building the server. I can't use my driver,
neither the generic fbdev driver.

Any ideas ?

Thanks
