Here is the info you requested:
r8169 Gigabit Ethernet driver 1.6LK loaded
eth8: Identified chip type is 'RTL8169s/8110s'.
eth8: RTL8169 at 0xa0000000800b7000, 00:40:f4:96:fc:3f, IRQ 131
r8169: eth8: Config2 = 0x01
r8169: eth8: link up
My p630 has 64bit PCI-X slots, but my r8169 adapter is a 32bit adapter. See
lspci output below (with a 64bit PCI-X e1000 adapter as a comparison).

I think my AMD64 system at home has a 64bit integrated adapter, as the
performance on it is 2.5x faster (either that or r8169 and ppc don't play
well together). I will verify this when I get home.
