your BIOS allocate that to your nic, and also it put that in reserved
in e820 table.

so before 2.6.28. kernel will allocate another resource to your BAR.

for 2.6.28, it change to honor PCI BAR than others...and at same time
use reserve_region_with_split ...
put the overlapping to reserved..

so solution will be:
1.rework reserve_region_with_split not to put the overlapping to reserved...
2. or update pci_request_region to check if conflicts is with name "reserved"

BTW:
please send out
dmesg -s 262144 > dmesg.txt
