Well I don't think that would be a problem and if we are talking led's
its not going to happen more than a few time a second you have to see
the thing flash. I don't want more code in the kernel than absolutely
necessary all it takes is one bug.

If you really want to make something that can't be done other than in
the driver it's some type of streaming mode and then you have to have
timers to control the speed. Think any card that needs to program sram
based FPGA it would probably go many times faster than todays interface.
