Problem with nForce Go 430, no link detected

Hi, I've got a problem with my laptop's ethernet features which is provided by a nForce Go 430, when I connect it on some other ethernet devices it can't detect the link.
All the devices were tested and work perfectly but let's see an example :
In my new student room I've got a RJ45 connector on the wall which out directly on a switch. When I connect my xbox link is established and I can get an IP address as the difference when I connect my laptop ethtool tells 'Link : no'. With a linksys' WRT54G it's the same thing, works with xbox (or other device) but not with my laptop. And of course when I plug my laptop on xbox all works like a charm.

I've discovered this problem one year ago under windows before installing linux and I had managed to fix it with disabling autoneg in nForce driver's setting and forcing to 100baseT/Full (or Half can't remember). Of course it doesn't work on linux.

I use forcedeth driver version shipped_with_lastest_kernel26 (you can see that I'm using kernel26 package), ethtool and mii-tool drive me crazy :

ethtool without any option :

[root@Savarah anarx]# ethtool eth0
Settings for eth0:
        Supported ports: [ MII ]
        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: Unknown! (65535)
        Duplex: Unknown! (255)
        Port: MII
        PHYAD: 31
        Transceiver: external
        Auto-negotiation: on
        Supports Wake-on: g
        Wake-on: d
        Link detected: no

Setting 10/100 half/full (all tested) :

[root@Savarah anarx]# ethtool -s eth0 autoneg off speed 100 duplex full
[root@Savarah anarx]# ethtool eth0
Settings for eth0:
        Supported ports: [ MII ]
        Supported link modes:   10baseT/Half 10baseT/Full 
                                100baseT/Half 100baseT/Full 
        Supports auto-negotiation: Yes
        Advertised link modes:  Not reported
        Advertised auto-negotiation: No
        Speed: Unknown! (65535)
        Duplex: Unknown! (255)
        Port: MII
        PHYAD: 31
        Transceiver: external
        Auto-negotiation: off
        Supports Wake-on: g
        Wake-on: d
        Link detected: no

As you can see nothing happens and cable were plugged for both operation

Mii-tool is more expressive :

[root@Savarah anarx]# mii-tool 
SIOCGMIIPHY on 'eth0' failed: Operation not supported
no MII interfaces found

isn't it ?

Here's my dmesg, lspci -vvv and ifconfig :

PCI: Setting latency timer of device 0000:00:14.0 to 64

Note some TX on ifconfig, I don't know where they come from.

If someone got an idea I don't know what to do, considering that it works with some ethernet device and with all on windows after disabling autoneg I don't think of an hardware failure. I'm ready to try everything (well not really everything but many thing ). Thanks in advance
