So can someone with access to details of the 945GM tell me if MSI interrupts should work, and if so if there's some internal registers that need to be poked to enable it (beyond what pci_enable_msi() does). It's not super-urgent-- I just like using shiny things like MSI, and I already have ahci, iwl3945 and e1000 working with MSI on my laptop, so the graphics are the only thing left with an MSI capability that's not working.
