You can forget your way of partition detection then if devfs is enabled and
running. You'll get not hda, hdb, but:
Yeah, one can build scripts to circumvent this, but this has to be done. :-)
We (Kai and I) had several problems with his devfs and partition recognittion.

I get from /proc/partitions
Now I want the model for this disk.
Where in proc can I find this information, unless I remap it back to hda/b ?!
