Bug#605450: linux-image-2.6.32-5-amd64: Please support and update multitouch driver of Macbookpro 7,1.
Package: linux-2.6
Version: 2.6.32-28
Severity: normal
Tags: patch
Hi,
Current Linux-2.6 package does not work multitouch device of Macbookpro 7,1.
This is because driver does not support a multitouch protocol of Macbookpro.
The patch revising this problem is already taken in by upstream.
6f2701b79f2ee0c5eb946e8a87993acbe8041da3
I confirmed that I made the linux-2.6 package which did this patch
applied, and a problem was revised.
Could you apply this patch in Debian?
Best regards,
Nobuhiro

Subject: [PATCH] Input: bcm5974 - report ABS_MT events
Make bcm5974 report raw multi-touch (MT) data in the form of ABS_MT events.
[dtor@mail.ru: get rid of module option, always report all events]
