Any chance to add DSP speed tuning? This allows the DSP to be locked to a max frequency of 133 to allow the ARM to stay at 400 when audio is active. This is nice when listening to MP3s and browsing the web.

See here for details. The kernel is under the section PPTP client and kernel with MPPE support. Then look at N800/810 - IT2008 version 5.2008.43-7 (latest Diablo).

The changes define a tunable, /sys/power/op_dsp, 0 is 400/133, 1 is 330/220.

thanks,
Frank
