   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 at pci0:10:0:	class=0x020000 card=0x82b31043 chip=0x054c10de rev=0xa2

    vendor   = 'Nvidia Corp'
    device   = 'MCP67 Ethernet'
    class    = network
    subclass = ethernet

$ ifconfig nfe0
