Sorry, I missed:

Looks like 02e8 is missing (see /proc/ioports below).


I also tried the patch on my ICH7 desktop which gives:
pci 0000:00:1f.0: quirk: region 0400-047f claimed by ICH6 ACPI/GPIO/TCO
pci 0000:00:1f.0: quirk: region 0500-053f claimed by ICH6 GPIO
pci 0000:00:1f.0: ICH7 LPC Generic IO decode 1 PIO at 0680 (mask 007f)
But 0680 is accounted for in /proc/ioports:
0680-06ff : pnp 00:06

Cheers,
FJP
