   Try backing out a rev or two. Well, try backing out one rev of
   if_nfe.c (back down to 1.30) and see if that works ok.

 Nope. Same problem occurs. Btw, is it required to rebuilt the whole
 kernel, or is it enough to just "make && make install" in an already
 compiled "sys/compile/KERNCONFIG" directory?

Try if_nfe.c rev 1.24 if_nfereg.h rev 1.6 if_nfevar.h rev 1.3

No luck either! I can ping out, but not in, as before.

To rule out other possible problems, it works fine when booting from a
FreeBSD 7.0 cdrom.

Give me the output of 'ifconfig nfe0' and the dmesg, if possible.

Here is pciconf, ifconfig and dmesg output:

$ pciconf -lv | grep -A4 '^nfe0'
nfe0@pci0:10:0: class=0x020000 card=0x82b31043 chip=0x054c10de rev=0xa2 hdr=0x00
vendor = 'Nvidia Corp'
device = 'MCP67 Ethernet'
class = network
subclass = ethernet

$ ifconfig nfe0
nfe0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> mtu 1500
	ether 4f:ad:6d:c6:1f:00
	media: Ethernet autoselect
	status: active

$ dmesg | grep nfe0
