I dug deeper in this second problem.
In fact it has not been solved by the 2.6.17-rc5 kernel.

I misinterpreted the result as i inadvertedly changed bluetooth dongle
at the same time.
So issue with wrong pin code only arise whith Sony Erisson(TI) + ST + bluez.
Sony Erisson(TI) + BCM + bluez works.

As you said issue is clearly seems to come from the hardware (LMP).

Yeah sure but from the kernel point of view there is a a level parameter
passed to setsockopt/getsockopt which is already ignored... or maybe you
were just speeking about user space ?
