Re: [tied] IE etymology for Achaia?

In his online revision of Frisk (on http://www.indoeuropean.nl), Robert
S. P. Beekes writes: "The name Akhaioi < Akhaiwoi (cf. Lat. Achîvî) is
known from Egyptian sources as 'q'jw'š', read as Aqaiwaša. Also in
Hitt. Ahhiya, later Ahhiyawâ, from *Akhaiwia or *Akhaiwa(?); Kretschmer
Glotta 21, 227). Against this Sommer (Ahhijavâ-Urk., A. u. Sprw., IF
55, 169ff.). The equation is now generally accepted, but the Hittite
form has not been satisfactorily explained. (Worthless Finkelberg,
Glotta 66, 1988, 127 - 134, who derives the Greek form from Hitt.
Ahhiyawa (!), with h2y > kh.) - The name is no doubt a Pre-Greek name
(Akaywa?). On the historical side Lehmann, Historische Zeitschr. 262,
1996, 1 - 38; Niemeyer Aegaeum 19, 1999, 141-155."

It schould be added that Ivo Hajnal argues that Hittite Ahhiyawâ /
Hiyawa is an epichoric Anatolian name and *not* a transcription of
Mycenaean Greek *Akhaiw(i)a (Troja aus sprachwissenschaftlicher Sicht
(Innsbruck 2003), pp. 35-42).
