Thank you very much Kay,
does libata work as a kernel module only or can be statically included 
into the kernel? My lsmod output is:

# lsmod
Module                  Size  Used by
vboxpci                11426  0
vboxnetadp             17099  0
vboxnetflt             13500  0
vboxdrv              1754521  3 vboxpci,vboxnetadp,vboxnetflt

that are Virtual Box modules. I've included into the kernel usb, sound, 
network, sata, ide, and other devices support. Modules are ppp, usb 
specific drivers, lp ... and others but not libata. Maybe should I 
looking for a more recent, backported to sqeeze linux kernel?

bye,
