pci_is_pcie() returns true for PCI-cards?

[Helge Deller <deller@gmx.de>]

In my machine I'm running two dual-DVI PCI video cards (NVidia GeForce 7300 LE PCI, ATI FireMV 2200 PCI).
Both are PCI and not PCI-Express cards.

Somewhere after kernel 2.6.34 the nouveau and the radeon DRM drivers switched their
initialization code to set the GART/aperture size to 64MB (for PCI) or 512MB (for PCIE),
and the pci_is_pcie() function is used to determine if the graphics card is PCI or PCIE.

In my case this broke both drivers for me, since pci_is_pcie() strangely returns true for my PCI-only cards
and (being neither a graphic card or PCI bus expert) both drivers set up a 512MB GART and then fail to 
function correctly.

Now my question:
My assumption is, that pci_is_pcie() should return true for PCI-E cards only.
PCI-only cards should return false. Is this assumption correct?
If yes, there is probably a bug somewhere and maybe someone here has an idea what I could test to fix this bug?
If not, then the nouveau and radeon drivers should not use pci_is_pcie() to determine if this is a PCI or PCI-E card...

I did some testing with kernel 3.1.5.
For the nVidia card (PCI 01:00.0) I got:
- pci_is_pcie(dev->pdev) = 1
- pci_find_capability(dev->pdev, PCI_CAP_ID_EXP) = 120
