udev/xen problem?

[Alastair Basden]

Hi,
I have FC6 and cannot get a serial modem working.  I believe that this may 
be because of a bug in the xen kernel: see 
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=204825

Does anyone know what the solution is?  Quite why I need a virtual kernel 
beats me... I'd just like to get the modem working...

The part solutions on the bugzilla page don't work, or at least, not my 
interpretation of them...

Is this bug still an issue in FC7 (which I'd rather not have to download).

Thanks.
