Aaaah ok that did the trick:) Now I understand what's going on!:)

Now I've got /dev/sd* for all the devices. But there's an inconsistence 
between the ordering of the names.

With the stock Arch kernel, I have:
/dev/sda = primary IDE disk
/dev/sdb = secondary IDE disk
/dev/sdc = the only SATA disk I have

With my kernel, I got:
/dev/sda = the SATA disk
/dev/sdb = primary IDE disk
/dev/sdc = secondary IDE disk

I've read, on the Arch wiki, the pages about consistent naming, but as far as 
I can tell, there's no track of it in my running system. I mean, 
in /etc/fstab the drives are mounted by device name, not by-label or id or 
uuid.

So I infer there's another reason for this, and maybe it has to do with the 
stock initramfs loading the modules in a certain order.
I'm not using an initramfs and no modules for scsi,sata etc, so, if that's the 
reason, I deduce I have to live with the different naming. But thit is based 
on a supposition: is it right?:)

Thanks also to Geir and Ryan for pointing me at the right direction:)

ciao!
