The errors were "fixed" by changing the configuration. Previously, I did not 
define CONFIG_AMD_IOMMU. As I have an AMD processor, CONFIG_INTEL_IOMMU was also 
not defined, which also meant the CONFIG_IOMMU_API was not defined. Once I added 
the AMD IOMMU parameter, the module compiled without problems.

As the previous kernel runs OK, I think the configuration is OK. I can 
understand that vboxpci could not run, but it should at least compile.
