I think that better yet is to examine vendor of device 0:0:0.
Something like:
dev = pci_find_bsf(0, 0, 0);
pci_get_vendorid(dev);

With all the checks and stuff.
Please keep in mind that there could be other vendors too (e.g. nvidia).
Also, access to the upper RTC NVRAM bank may be disabled in chipset configuration.
