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  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,
