Okay, I applied this additional patch, and by the increased memory usage (as shown by free) I concluded that it indeed works. However, I was still able to reproduce the issue without a single error being written to dmesg. :-(
I will try some really old kernels as Wey suggested to see whether it makes any sense to bisect it, but if it does, it might take more time than I can make free. Perhaps it would be cheaper to just get another card in that case. :-)
