I have tested Linus' patch and it makes a difference:

It still doesn't work.
It looks very much like a stuck bit, but at least we get a slightly
"better" error message and the expansion ROM now gets enabled. progress!
Linus wants to "debug this to death" (his words, not mine) but I don't
have access to the suspect hardware for the next five weeks, and it will
probably be serviced some time during those weeks.
Thank you for being patient, Linus. And sorry for not being able to
provide more debug data.
