PCI device problem - MMCONFIG, cannot allocate resource region, resource collisions

The kernel has a problem allocating resources for my PCI NIC. Here is what the kernel is reporting:

# uname -a

Linux wopr 2.6.20-gentoo-r8 #7 SMP Sun May 20 20:56:56 PDT 2007 i686 AMD Athlon(tm) 64 X2 Dual Core Processor 3800+ AuthenticAMD GNU/Linux

# dmesg
...
PCI: BIOS Bug:  MCFG area at e0000000 is not E820-reserved

I have seen other posts reporting similar error messages. I would like to help resolve this problem, and I can do some testing if needed. More info:
