Slightly OT, but not much:
I'm running Centos 4.4 on a Gigabyte GA-7N400 Pro2 board. This board has
a builtin RTL8169 chip. When I do lsmod I get (among other things)

	r8169                  19913  0
lspci shows:
	01:0b.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8169 Gigabit Ethernet (rev 10)

and "ethtool eth0" shows:
	Settings for eth0:
        Supported ports: [ TP ]
        Supported link modes:   10baseT/Half 10baseT/Full
                                100baseT/Half 100baseT/Full
        Supports auto-negotiation: Yes
        Advertised link modes:  10baseT/Half 10baseT/Full
                                100baseT/Half 100baseT/Full
        Advertised auto-negotiation: Yes
        Speed: 100Mb/s
        Duplex: Full
        Port: Twisted Pair
        PHYAD: 0
        Transceiver: internal
        Auto-negotiation: on
        Link detected: yes

And FWIW, dmesg shows:
	r8169 Gigabit Ethernet driver 1.2 loaded
	ACPI: PCI interrupt 0000:01:0b.0[A] -> GSI 16 (level, high) -> IRQ 201
	r8169: NAPI enabled
	divert: allocating divert_blk for eth0
	eth0: Identified chip type is 'RTL8169s/8110s'.
	eth0: RTL8169 at 0xf8832000, 00:0d:61:3f:5f:c3, IRQ 201

Centos 4.4 is a 2.6 kernel (2.6.9-42.0.2.EL) (though an older one than
FC5 uses, I believe).  I'm not running the network at gigabit speeds,
but it looks as if it would be expected to work, with that driver, were
I attempting it, based on the ethtool output.

So. My point is: I don't think the r8169 module is necessarily the wrong
