Update:

compiled mdadm.static on a 32bit machine and could re-add the two
partitions to the array! cool! thanks, Neil!

~500 mins to wait now.

Do I have to fear read-errors with RAID5 now?

I still don't fully understand if there are also 2 bits of
parity-informations available in a degraded RAID6 array on 2 disks only.

Thanks again so far, hoping the best now ;-)
