[SeaBIOS] Graphics card pass-through working with two pass pci-initialization

Hi Folks,

Could anyone give me a 101 lesson on what is "two-pass PCI initialization"?

I tried some time ago to pass a LSI megaraid to a rhel5 guest, but the
initialization of the pci device inside the VM fails (because, I think, it
was already initialized in the host).

Just wondering could that be related? Have anyone tried passing a raid card
to the guest?
