Oh, right "blacklist" actually works differently than I was
remembering. But this should work:

alias pci:v00008086d0000A0EDsv000017AAsd000022D5bc0Csc03i30 letsmaskthisone

if you do that, then the kernel requesting that modalias will tell
modprobe to load letsmaskthisone.ko but that does not exist, so it
will fail and not load anything.
