I attached them to <https://bugzilla.redhat.com/show_bug.cgi?id=1226928>

If the drivers are installed during the initial setup, both ISO and VFD
work - after navigating into the right sub directory and enabling "show
not matching drivers". No BSOD.

Using the same ISO after doing the install using the emulated IDE, the
drivers are rejected with:

Answering my own question: .crt files are DER encoded. "dumpasn1" shows
them to contain PKCS#7 data.

I filed <https://bugzilla.redhat.com/show_bug.cgi?id=1226928>. If
anything is still missing, just ask.

Thanks for the fast help and for any more help in advance
