I sprinkeld a few debugging messages around in the code and looking at that
I don't see how the code can enable NMSI for device 00.0, but not for 09.0:

Both will exit here:

if (host_bridge == dev && host_bridge_with_leaf(host_bridge))

in nv_ht_enable_msi_mapping, so it seems host_bridge_with_leaf returns true 
for both. I think because my hw configuration changed a bit (inserted one
PCIe card) comparing to last time I tested old v4 version, this doesn't work
anymore - so the leaf check alone is not realiable, I guess. For me adding
something like this, makes it work: (I hope the description makes sense, as
I am just refering to the function names and trying to guess its meanings.)

Patch is against linux-next branch of pci tree.

[patch] pci: enable MSI on host bridge without checking for leaves

On C51 the host bridge needs to be enabled, but the MCP51 host bridge not.
So don't check for leaves on the main host bridge.

seems it is not right, it may enable your 09.0 again.

No if you look into the whole function, you'll see that host_bridge is device 
0:0.  (	host_bridge = pci_get_bus_and_slot(0, PCI_DEVFN(0, 0)); )

As I said this time there is a PCIe device more in my system (a realtek NIC):
I guess because of that this one appeared - or I have some different drivers
loaded?
