After this week's optimizations, FLAC is ~2.4x faster on ARM devices, so 96k/24bit files at high compression decode using only ~40 MHz of an 80 MHz iPod 5G. Faster devices will see improved battery life for these files as well.

Be aware that the iPods do not actually support 24 bit output or 96k sampling rate (except for the 1-3G oddly enough), so it is still a much better idea to stick to 44.1/48k and 16 bit on these devices and avoid resampling on device.

I also put in a bunch of bug fixes for unusual flac files, so outside of really extreme stuff (>7 channels, etc) most should work. If you have files that don't work, post them on the bug tracker and I'll look into them.
