I've took a closer look at this whole mess - and it's just a mess.
- Archos SDE has wpa_supplicant source 5x, on archos we have 6x.
- On archos there is wpa_supplicant that supports tiwlan driver (witch is not a part of wpa_supplicant itself), archos SDE source does not have this driver - it's a custom lib (but available in android source...)
- Archos wifi does not work with compiled (without modifications) wpa_supplicant from SDE set, with 6.1 version either (patched or not).
- Even OMAP documentation said nothing (or i haven't found) about tiwlan driver - they use in examples wext driver
this certainly sux - (like a whole wifi "design" or it's lack)
