    Subject[patch 07/16] ide-disk: Fix LBA8 DMA
    From: Daniel Drake <dsd@gentoo.org>

    This is from Gentoo's 2.6.11 patchset. A problem was introduced in 2.6.10
    where some users could not enable DMA on their disks (particularly ALi15x3
    users). This was a small mistake with the no_lba48_dma flag.

    I can't find the exact commit but this is definately included in 2.6.12-rc4.
