Just for the record, the problem is now "solved".

For some reason, RA0-RA2 did not work as inputs. They interfaced bad
with any output-port on the 16F887. I found this out by manually
"hijacking" the datalines and cross coupled the (not) intended ports,
and found that test #1-3 did not work under any circumstance when
connected to RA0-2, but flawlessly when connected elsewhere. Tried to
change the IC in case it was damaged, but I got the same weird
behaviour on other chips as well.

So, I moved RA0-3 to RC1-3. Works as a charm, but I have no clue as to
why RA0-2 didn't work as inputs, despite comparators/vrefs/analogs etc
turned off.
