it seems that the first problem is:

arch/x86_64/kernel/built-in.o: In function `pci_iommu_init':
pci-gart.c:(.init.text+0x8f0c): undefined reference to `agp_amd64_init'
pci-gart.c:(.init.text+0x8f1a): undefined reference to `agp_bridge'
pci-gart.c:(.init.text+0x8f1f): undefined reference to `agp_copy_info'
make: *** [.tmp_vmlinux1] Error 1

Is this fixable or will the intelfb never work on x86_64 system?

Regards

Marcel
