But *why* is Vista not showing the symptoms?

The R40e was released in 2003. The idea that it has initial Vista 
support is just horrifically unlikely. The issue is that the invalid 
values in the table were never caught because, for some reason, Windows 
never used them. The bug is that we're not using the same heuristic as 
Windows. Applying a static list of hardware just results in it being 
likely that we'll never fix that bug.
