Subject: [PATCH] Fix an old sky2 WOL regression

Wake-On-Lan was broken for a few systems with commit
87b09f1f25cd1e01d7c50bf423c7fe33027d7511 more than a
year ago.

This commit fixes the regression for the AOpen i915GMm-HFS
motherboard. It reintroduces the old code, but that code is
only executed for those system included in a dmi_system_id
list. Currently there is only one entry in that list, but
it probably will grow.

You might also want to check with AOpen to see if there is a BIOS
update. Often the BIOS programs bits on the onboard card to deal
with power management issues.

[I added some people to the cc list that commented on bug #19492]

The last BIOS AOpen published for that board is more than six years old.
No. I will not bother them with this problem.

Your commit broke existing support for WOL on a number of boards.
This is known to you and to bugzilla.kernel org since 2010.  A number of
people complained about that, but nothing happened.

Neither your original commit description nor the description of the
PXE_LegNat_Sel I found at other places indicate that setting
PXE_LegNat_Sel could do any harm.

Stephen: It´s a real regression, the fix is known. If you do not want
to go back to setting PXE_LegNat_Sel, you really should allow
dmi_matched fixes.

Mirko, Ralph: Any comments from Marvell?
