Kernel version?  System?  Processor?  What 'lspci -vvv -s 01:00.0' reports ?

Function pci_resource_start() reported zero, and matroxfb believes that
it is illegal.  If you are using ia32/x86_64/ia64, it is almost definitely
illegal, with ppc/ppc64 maybe NULL pci_resource_start() is valid and in such
case just remove tests for ctrlptr_phys == NULL and video_base_phys == NULL
from drivers/vide/matrox/matroxfb_base.c.
