I think the following lines are suitable for other bridges besides
nvidia's, :) :
===================
+ if (pci_enable_msi_ht_cap(dev) != 0) {
+ return 0;
+ } else {
+ /* Get upstream bridge device handle */
+
+ bridge_dev = dev->bus->self;
+ while(bridge_dev != 0) {
+ if (pci_enable_msi_ht_cap(bridge_dev) !=
0) {
+ return 0;
+ } else
+ bridge_dev =
bridge_dev->bus->self;
+ }
+
+ return 1;
+ }

Isn't there a way we can make this work for any upstream HT bridge,
rather than only for specific NVIDIA chipsets?
