Done on the current tablets, as well as it can be done on the current tablets (what with audio mixing being done on the DSP), and it will be supported out of the box afair on the new tablets, so probably best to strike this one off the list.

+1 ARM kernel-side audio codec drivers for the hw in the n810 and n800 (the n800 ones exist, if anyone fancies porting that across for the n810 that would be good).

Speaking of which, I understand from Solca that the cpufreq stuff for OMAP2 devices in the latest kernels (latest main releases, not what's running on the tablets that is) is deprecated/removed (due to lack of support); keeping the OMAP2 alive in the current kernels would be another worthy goal.
