Yes, a very interesting question!
The three approved amendments define new PHY layers. All of the
currently defined PHYs share a maximum PSDU size of 127.
There are some added MAC features to support new PHY features but the
basic MAC has not changed.
Perhaps a more specific question is, what features of the PHYs and MAC
does 6LoWPAN depend on to work?

P802.15.4-2006 alone is not the current standard: There are three approved
amendments and so the current standard is P802.15.4-2006 plus the three
amendments approved (P802.15.4a-2007, P802.15.4c-2009 and P802.15.4d-2009).
You need all 4 documents to know what is in the current standard.
So one interesting question would be -- does 6LoWPAN (RFC 4944 - HC1/2 + HC +
ND) work with all these?
