I have some code which I'm planning to put into the kernel at some point
which does soft-autorepeat (it ignores any hardware repeat that the keyboard
may do in any mode other than RAW).

I cooked up this patch because:

1. Some keyboards on ARM hardware do not autorepeat
2. I got annoyed with the behaviour you describe above, except I was
   using 4 computers, and rebooting one of them resets the keyboards
   parameters.

I haven't submitted it to Linus yet because the delay and repeat rates
are currently #define-coded into the code, and therefore are not run-time
configurable (maybe someone would like to fix this?).

Which kernel version are you using?
