This one useses a:
none0@pci0:0:0:0: class=0x050000 card=0x02f010de chip=0x02f010de rev=0xa2 hdr=0x00
vendor = 'Nvidia Corp'
device = 'C51 Host Bridge'
class = memory
subclass = RAM
At least Linux doesn't seem to avoid using MSI with these.
I didn't get any further regarding the other report so far.
