------- Comment #20 from [EMAIL PROTECTED]  2008-01-11 20:09 -------
Hi Jean, Bjorn,

In 2.6.24-rc7-git3 I expect that the it87 driver on these boards
is still not loading.  For Shaohua's workaround from comment #1 isn't
applied, nor is Bjorn's workaround from comment #17 -- while
the initial PNP patch that sparked this is still present (as it must be).
(Indeed, one could argue that the PNP fix should again be pushed
 into 2.6.23.stable, since it fixes far scarier potential system failures
 than the it87 driver failing to load.  But with side effects such
 as this, any such change perhaps may exceed .stable's risk tolerance...)

I've read through the thread and I concur with the things
that Bjorn wrote about how ACPI works.  It is likely that the
BIOS is reserving this device for its own use, and unlikely
that the BIOS will ever declare a device for the purpose of the OS
to bind a native driver to this hardware.  While it is never a good bet
to assume a BIOS writer is doing something correctly, one could
argue that by not loading it87 on these boards, we are obeying
what the BIOS writer asked us to do.

Do you think that this problem is widespread and will effect
virtually all boards where it87 used to work, or do you think
it is a small subset?  Does anybody know if a native driver for it87
exists on Windows and if it loads on the systems at hand?
