These settings are only present on the newer targets. The archos
targets have too little RAM to make dircache feasible. So the
only option on archos is to keep tagcache on disk, that's why
there is no setting.

Hmm, it seems something is going wrong with the tagcache build
and/or commit. The file tagcache_tmp.tcd shouldn't exist anymore
after the commit on boot. Instead, you should find

tagcache_N.tcd (where N=1..6) and
tagcache_idx.tcd

While building tagcache takes a while on archos, it should work
fine once it's built. On my recorder v1, the initial scan ("force
tagcache update") takes around 17 minutes, the commit on next
boot (counting from [1/10] to [10/10]) takes around 1.5 minutes.
After that, the tagcache is usable, and subsequent boots are as
fast as without tagcache. My unit has 4774 files on it (3330
music files), and 393 directories, according to the stats plugin.
