Intel video driver question - cards second function

[Jedrzej Solecki]

Hello,
I am reading the xfree86 video Intel driver source code and I have one
question (maybe stupid - I'm just a newbie:)).
I am asking about this piece of code (src/i810_driver.c:I810Probe()):

 /*
  * Mobile platforms may have both function 0 and 1 active, but they
  * are handled as a single entity.  To make sure that the function 1
  * entity isn't assigned to a screen, check for and claim it here
  * first.
  *
  * XXX If function 1's resources are ever needed, they'll need to be
  * added to the screen and marked active.
  */
 for (ppPci = VideoInfo; ppPci != NULL && *ppPci != NULL; ppPci++) {
    if ((*ppPci)->vendor == PCI_VENDOR_INTEL &&
        (*ppPci)->func == 1) {
       for (id = I810PciChipsets; id->PCIid != -1; id++) {
          if (id->PCIid == (*ppPci)->chipType) {
             /* Claim slot */
             if (xf86CheckPciSlot((*ppPci)->bus, (*ppPci)->device,
                                  (*ppPci)->func)) {
                xf86ClaimPciSlot((*ppPci)->bus, (*ppPci)->device,
                                 (*ppPci)->func, drv, id->PCIid,
                                 NULL, FALSE);
             }
             break;
          }
       }
    }
 }

I have a notebook with the 945GM controller with active functions 0
and 1. I would like to ask if this code:

             /* Claim slot */
             if (xf86CheckPciSlot((*ppPci)->bus, (*ppPci)->device,
                                  (*ppPci)->func)) {
                xf86ClaimPciSlot((*ppPci)->bus, (*ppPci)->device,
                                 (*ppPci)->func, drv, id->PCIid,
                                 NULL, FALSE);

should be executed in this case.
If yes then something is wrong because it doesn't:)
With the first function (PCI:0:2:0) this condition:
(*ppPci)->func == 1)
is not met and that's OK.
For the second funtion (1) this condition:
if (id->PCIid == (*ppPci)->chipType)
is never met because I810PciChipsets does not contain the
"(*ppPci)->chipType" value. There is only "PCI_CHIP_I945_GM
0x27A2" defined in the common.h .
But the second function's (PCI:0:2:1) chipType value is 0x27A6 which
is not defined in the common.h.
I would like to ask if this is not there on purpose and I
misunderstood this part of code or if there is something wrong:)
