[CentOS] Problems with BCM5709 network

I've just installed CentOS 5.4 on an IBM server with a BCM5709 network 
adapter, and can't get networking to work. It looks like an appropriate 
driver (bnx2) is installed, lspci and the system log return sensible 
info on the unit,  there are no specific error message anywhere, but I 
get "no link present" when I try to activate the device. In other words, 
I see essentially the same behaviour as when the network cable is 
missing, but I've tried several cables, connection points etc. and also 
get the appropriate indicator lamps etc. so I'm quite sure the 
connection is good.

Does anyone have any idea what may be wrong? If not, have any of you lot 
got networking to work with a similar setup?

Some extracts from the system log are included below...

Thanks,

- Toralf
