Thanks Gilles, sounds like it will be worth waiting for 2.6.4 before 
making another transition. From the maintainers' perspective I was 
thinking mostly of "did 3.10/3.14 seem more troublesome/likely to break 
than 3.8 when you were writing and testing it?". I take it from your 
reply that it didn't, and I didn't see any reports of issues in the list 
archives...so when 2.6.4 is ready I will give it and 3.14 a go.

I also saw your tip on the CS5536 boot param and the benchmark results 
in your other email. Thanks for that, seems to work fine on my system.
