for some strange reasons, the sd_mod module doesn't initialize correctly, as a 
result, the kernel doesn't know how to use scsi discs.

Yep. of course it can't boot from a scsi disc then..

I'd try to
a) compile scsi and scsi-disc static into the domU kernel
b) test with using hda3 or something instead of sdc3 in the domain config, to 
see if your root-filesystem works at all
