Microsoft Lifecam VX-1000 microphone doesn't work

Microsoft Lifecam VX-1000's microphone (which uses the gspca driver) never worked in Linux.
Upstream kernel 2.6.26 was released yesterday and fixes this problem.
I have tried to track it down and it seems that this one http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=19697b546c9bc5b3c44070be1cfc7ce54a97c0d9 does the trick.

It would be great if the kernel team could backport this do Maverick's kernel.
