1) Sorry, I don't have a PPA or similar kernel image for you to try.

2) I expected that Windows would move 00:1f.5 BAR 0 to be inside the
windows reported by the PCI0 _CRS, but the AIDA64 report shows
otherwise:

    B00 D1F F05:  Intel Ice Point-LP PCH - SPI (Flash) Controller
                  
      Offset 000:  86 80 A4 34  06 04 00 00  30 00 80 0C  00 00 00 00 
      Offset 010:  00 00 01 FE  00 00 00 00  00 00 00 00  00 00 00 00 

BAR 0 is at offset 0x10, and it still contains the value BIOS put there
(0xfe010000).

I don't know why Linux couldn't find space for 00:1f.5 BAR 0.  Tracing
the resource assignment code with 'dyndbg="file drivers/pci/* +p"' and
possibly some new trace messages might give a clue.

When Linux fails to assign space, it tries to revert to the BIOS
assignment ("BAR 0: trying firmware assignment [mem
0xfe010000-0xfe010fff]").  Apparently we declined to use that BIOS
assignment because it "conflicts with Reserved [mem
0xfc800000-0xfe7fffff]".  Perhaps Linux should ignore that conflict.

That "Reserved [mem 0xfc800000-0xfe7fffff]" comes from the E820 map, and
the Linux handling of that map is somewhat haphazard.
