Please ignore my previous comment. It turned out that linux-image-2.6.27-10-generic (Version 2.6.27-10.20) is indeed in the intrepid-proposed repository, and it does fix this bug. It is a dependency of linux-image-generic (Version 2.6.27-10.13). I don't quite understand the reason behind the different numbering, but whatever. The bug is fixed, thanks a lot :-)
