Thanks for the tip, but it doesn't (necessarily) seem to be the case 
with our box.
I do have /dev/xen with:

[root@dom0-0-50-45-5d-59-aa ~]# ls -als /dev/xen/
total 0
0 drwxr-xr-x   2 root root       80 Sep 19 17:43 .
0 drwxr-xr-x  13 root root    14100 Sep 19 17:37 ..
0 crw-------   1 root root 254,   0 Sep 19 17:43 blktap0
0 crw-------   1 root root  10, 201 Sep 19 17:36 evtchn

But there's nothing in /dev with major 254.

Roland
