Thanks for helping me out with your experience - I'll check and come back to tell about the result.

OK, I promissed to come back with the results:
I checked the waitrequest and found that in my case it is actually active for up to 4 milliseconds! :(
So then I put other signals in the write timing chart into question:
In the chart the write signal stays active over the whole process of writing data. I wondered if that was actually required. So what I did was to convert it into a strobe signal that is just active for a single clock cycle just the same way as the control registers gets written.
And Bingo! That seems to solve my problem! :)
The whole data is written within one second and it seems that it is realiably flashed into the memory (I have to run more tests to assure that this is actually true). :cool:
So I can only recommend not to follow the Altera flash memory user guide too closely!
edit: the above observation is not entirely true! see my next post below!
