That's news to me.  Only SLES9 had that 'feature' as far as I know.  All 
SATA disks in recent 2.6.x kernels are treated as SCSI disks with SCSI 
(/dev/sd*) block device names.  The sata_sil driver certainly falls into 
this category (except on SLES9).

Somethihng is very broken on this system is he has to forcibly rescan the 
scsi bus to detect drives that were connected since POST.

There is none.  PATA is legacy IDE (good ole IDE with the wide fat cables, 
etc).  I think you're comments above were confusing PATA with SATA (other 
than the retardation from SLES9).
