With the standard Kernel i didn't have access to my harddisk, because i have the SCH Poulsbo controller (see title).
Please use: < lspci -k > to see your hardware.
I now recompiled the Kernel with following additional information < CONFIG_PATA_SCH=y >. You can found this entry under: -> Device Drivers --> Serial ATA (prod) and Parallel ATA (experimental) drivers ---> Intel SCH PATA support
