kernelparameter idex=noprobe

[Markus Kossmann]

Hallo,
according to linux-2.6.4/Documentation/ide.txt :
"idex=noprobe"         : do not attempt to access/use this interface
SuSEs inofficial 2.6.4-0 kernel ( precompiled from rpm) comes with 
CONFIG_BLK_DEV_SIIMAGE=y
CONFIG_SCSI_SATA_SIL=m

Trying to use the sata_sil driver for my sil3112 controler I did give
ide4=noprobe ide5=noprobe hdi=noprobe hdj=noprobe hdk=noprobe hdl=noprobe
on the kernel commandline

The Bootup- messages show:

Why is the SIL3112 taken over by the siimage driver ?
Did I misinterpret ide.txt, is ide.txt wrong or is this a bug ? 

hdi=noprobe seems to work however. The attached SATA disk doesn't show up.  
And it does show up if I leave out hdi=noprobe. 

Is there any chance to use sata_sil with that kernel configuration ?
Or is recompiling with CONFIG_BLK_DEV_SIIMAGE=m or with siimage disabled the 
only option ?
