There is no need to add libata.force=noncq to kernel command line for normal booting with AHCI mode!
It seems to be the latest linux 2.6.32-rc6 kernel supports NCQ mode for Acer 3810T (it's all about Hitachi HDD)! Also my booting speed is 32 second now after 40 seconds on 2.6.31 kernel.
I also hope that enabling NCQ feature now will increase battery life on 3810T (now it's only 4,5 hours for me versus 7(!) on Windows 7)
FINALLY!
