[Avodah] : esav

[SBA]

rom: "Eli Turkel" 
Rashbam also takes a very positive attitude towards Esav that the 400
men with him were an honor guard and that he was genuine in his good
feelings towards Yaakov.

I learned that today - listening to a CD of a Parsha Shiur which was given
nightly by Reb Yankele zt'l, the Pshevorsker rebbe in Antwerp.

He expresses great astonishment at this Rashbam. 
1) Because the Rashbam usually goes for posheter pshat, and 
2) What is the Rashbam's source for this?
