Well, I don't know if that will be helpful.  Humm, maybe a dmesg?

Ok.  First remove device bge in your kernel config.  For example create a
config file with:

>>> BEGIN
include		GENERIC
ident		MYKERNEL (or what you like)
nodevice	bge
<<< END

After rebuilding and installing your kernel,
you can do something like that:

pciconf -w pci0:28:2 0xd8 0x04110008

pciconf -w -h pci0:28:2 0x58 0x0000

pciconf -w pci0:28:2 0x24 0x0001fff1
pciconf -w pci0:28:2 0x20 0xc830c830

pciconf -w -h pci0:28:2 0x04 0x0007


After that, you should be able to kldload if_bge and report back if
this work.  In that case I will modify the DSDT so that you won't to
worry about all of those pciconf stuff.

Good night!
