Fix IDE CD-drive PIO mode.
CD drives in PIO mode don't work under Xen because of a change in Linux
between 2.6.12 and 2.6.16, as a result of the following thread:
http://lists.parisc-linux.org/pipermail/parisc-linux/2005-August/027197.html

The change breaks systems which have highmem and a swiotlb because the
ide-cd driver doesn't use the swiotlb, resulting in read/writes to/from
highmem pages in PIO mode not working any longer. Xen kernels usually have
both highmem and a swiotlb.

2 ===========
4 The xen-bugtool command line application will collate the Xen dmesg output,
5 details of the hardware configuration of your machine, information about the
6 build of Xen that you are using, plus, if you allow it, various logs.
8 The information collated can either be posted to a Xen Bugzilla bug (this bug
9 must already exist in the system, and you must be a registered user there), or
10 it can be saved as a .tar.bz2 for sending or archiving.
12 The collated logs may contain private information, and if you are at all
13 worried about that, you should not use this tool, or you should explicitly
14 exclude those logs from the archive.
16 xen-bugtool is wholly interactive, so simply run it, and answer the questions.
