Subject: gspca for_2.6.36 - maybe does not work properly for me

I am Sony PS3 Eye webcam user. 

After installing 2.6.36 this camera gets recognized but actually does
not work. It might be some own stupidity of improper kernel
configuration but I cannot track it down at moment.

relevant dmesg:

No image is produced with any webcam software I have tried.

Kernel config is too big to be posted here, so I skip it.

I have tried same on different computers with Intel integrated video and
NVIDIA propietary stuff to ensure I have all right with video side.
BTW new PS3 Eye (looks same but product code is different, price is
lower) is released in Japan and I get my hands on it today later. Then I
check if old driver works at all etc.
