It appears that MSI does not work on either G5 PPC nor on a E5500-based platform, where other hardware is reported to work fine with MSI.
Both tests were conducted with NV4x hardware, so perhaps other (or even this) hardware can be made to work. It's still possible to force-enable with config=NvMSI=1 on load.
