[opensuse-kernel] driver load question

Hi, I've asked this question on the opensuse list but was met with silence.
I have had an intermittent network connection problem since new with my msi 945GCM7 ICH7 motherboard with RTL8111C giglan. This problem has spanned factory alpha to present 11.0 retail with 2.6.25.9-0.2 kernel.
After boot although everything reports as working, my network won't connect. Sometimes restarting the network will make it work but most times not. If it is not working ethtool reports a speed of 1000Mb/s, if it is working a speed of 100Mb/s (router speed) is reported. I found in the beginning, starting with the NIC off in the bios and then rebooting with it on made it work but not always. I have changed cables etc.
I compiled the r8169 driver into the kernel and this has solved the problem 99.9% but I have to recompile after every kernel update and still have to reboot when 0.1% of the time.
The problem occured yesterday so I decided to check good and bad boot logs and found the revision number was 0xFF when the nic doesn't work and 0x02 when it does.
The relevant lines from log:-
done eth0 device: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI
Express Gigabit Ethernet controller (rev ff)
eth0 IP address: 10.0.0.54/24
doneSetting up service network . . . . . . . . . . . . . . .

Express Gigabit Ethernet controller (rev 02)
eth0 IP address: 10.0.0.54/24
doneSetting up service network . . . . . . . . . . . . . . .
.done
What can I check for next? I enabled KDB on last compile but I have no experience using it, how would I setup a breakpoint when the incorrect version number is loaded?
