Sorry for my late reply.
Now ,i discovered that great part of performance loss was caused by  a
mis-configuration
in Kernel-file. (wdc instead of pciidee ..... :( ).
But still i cannot obtain the full-speed of my controller.
In fact even if if my motherboard is UDMA/66 capable ,pciide insist to
recognize it as UDMA/33
The chipset is a VIA VT82C598MVP.

this is the dmesg:
