I don't think Beim deals with this exact variation as on p57 white plays e3 before Bf4. That black still has to be extremely accurate isn't a good omen, though I can't say I've had much trouble with this line...
I did some searching in my other books and found some kind of remedy, though I think it's a bit optimistic with =+ after move nine.
Anyway, Kindermann offers some hope with the following game - guess who's playin' black!

1.d4 f5 2.Nf3 Nf6 3.Bf4 g6 4.h3 d6 5.e3 Bg7 6.Be2 0-0 7.0-0 Nc6! 8.c4?!
[8.d5 e5! with either a good king's indian or nice compensation for a pawn. However, after 8.c4 Ne4 9.Bh2 e5 10.d5 black (a YUG GM) played 19...Nb8 in the last game below. So how good is that 'good king's indian'?]
8...Ne4! 9.Bh2 e5' =+' Kindermann 10.a3? exd4 11.exd4 Qf6'-/+' Kindermann 12.d5 Qxb2 13.dxc6 bxc6 0-1 [13...bxc6 14.Nbd2 Nc3-+]
So it seems that Kindermann doesn't take this variation as seriously as it may deserve. But so far 7...Nc6! does look like black's best.
There are few games available with ...Nc6, but so far black has scored alright at least
