There appear to be two problems with the inf files, from a BartPe perspective.
The first, as you have noted is that device is not listed.
The second is the way the supported OSes are enumerated. BartPE gets confused by the info for all the other OSes.
In each of the Inf Files change the following lines as follows:
In the [Manufacturer] section change
%Intel% = Intel, NTx86.5.1, NTIA64, NTAMD64, NTx86.6.0
to
%Intel% = Intel, NTx86
Then change the [NTx86.5.1] heading to just [NTx86]
That tweak is going to vary a little per file - some of them you might be changing [NTx86.5.1.1] to [NTx86].
There is more info here:
