Unlike for CMOS/RTC, do detection very early, to avoid disturbing normal
operation later on.
Like for CMOS/RTC a fundamental assumption of the probing is that reads
from the probed alias port won't have side effects in case it does not
alias the respective PIC's one.

I appreciate what Jan is trying to achieve. I also share Roger's
concern about reading IO ports since we don't know what is there.
I also don't have a good alternative to suggest...
