To help clarify things -- the USB case is wrong. The patch enables the kernel to work around the problem.
I think the patch will work with the vanilla kernel as well as with the -mm kernel. You can try it and see.
Well. It does not work with vanilla-rc4+patch, just output pin timeouts, but it works with mm1 your patch applied.
Not testing with that, and still no luck: ftp://ftp.kernel.org/pub/linux/kernel/v2.6/testing/linux-2.6.9-final.tar.bz2

But it works fine with mm1 and your patch applied, not with other kernel versions, not rc4 vanilla and -final even patch applied.
