Thanks again for your help in this.  I assume current kernels still don't
work out of the box on your machine?

If so, please add a comment to [1] with the newest version you've
checked and your DMI information.  (You can get it with "dmidecode" or
"grep . /sys/class/dmi/id/*", or something like "dmesg | grep DMI" on
more recent kernels.)

Unfortunately some machines need to use the _CRS table and some need
it ignored, so for now upstream is building a table of known cases in
which the kernel looks up the machine at boot time.  Hopefully over
time patterns will emerge and there can be a more principled rule.

Hope that helps,
Jonathan
