Ah, I missed that earlier. Now, however, I've downloaded the driver from 
3ware.com, for kernel 2.6.18, but that seems to result in a kernel crash 
during the detection phase. :-\

That doesn't sound too promising at all. :-\ Did you try using the 3Ware 
supplied 2.6.18 driver?

Yes, I use a fairly complex setup with a firewall in a domU, multiple 
interfaces and a bridged/routed setup. Basically, I threw out all the 
bundled xen-networking scripts and wrote new ones from scratch.

OK - I'll take that into consideration, but given the time frames of 
this project, I probably have to stick with Xen one way or another. :)
