Ok, ok, I can take a hint. :-) I'll try to look into it later this month.
I tried 2.6.32.3 with Matthieu's patch on the ts7260 I have, and couldn't get
it to boot. (It just hangs after uncompressing the kernel.) I also tried adding
the "mem= mem= mem= mem=" stuff to no avail.
Has anyone had any success with it?

Thanks for the RT pointers, I'll try them out.
I think I'd be happy with deterministic delays - I want the multiplexing scan
to be regular, independent of load. I'll try twiddling the other options as you
suggest.
