I looked at your dmesg from 2.6.25.10
it tried to use mmconfig, and later fall back to conf1, because 1. your MCFG said it support bus [0,255], and range will be [0xf0000000, 0xffffffff] 2. firmware only reserve [0xf0000000, 0xf4000000)
and 2.5.25 will not check acp reserved range.
from 2.6.26, it will check if the [0xf0000000, 0xffffffff] is reserved via acpi dsdt _crs? it will fail too.
So MCFG table is broken.
You need to get firmware update from your vendor.
or we need to put that system on DMI check to change end_bus_number from 0xff to 0x3f
ps: mem=2g will not work, it will can not change mcfg table etc... you need take out 1G ram out.
