Unfortunately, it's a bit problematic to "save" all the output. I have not 
(yet) enough disk space to compile the kernel (sigh!). I use the 
vmlinuz-2.6.11.4-21.8-xen downloaded by the yast online update (which, I 
suppose, should be like the "default" one), and I recompiled the 
inirtd-2.6.11.4-21.8-xen in the same way I did for the "standard" one. I 
think I need the drivers for USB (uhci, ehci, ohci, usb-storage), for the 
pcmcia (yenta, pcmcia) and for the scsi disk (scsi, sd); and, actually, it 
works fine for the "standard" linux.  Maybe some "un- compatibility"?

Actually, the disk is really "old" and not at all "perfect" (it doesn't start 
immediately always when I connect the power supply) but, when it start to 
"run", it works normally with my "standard" boot and kernel....
Maybe it's a stupid question but... could I use the "standards" kernel and 
initrd with Xen?
