Just to confirm that I have same behavior here at T43 Ubuntu Hoary 
5.04. Kernel with SATA patches from thinkwiki. I thought it was an 
issue of my SATA/PATA pass-through but apparently not. Anyway I've been 
manually spinning down hard drive with 
hdparm -y /dev/sda
and since my laptop-mode enable me to spin down for 20 minutes it's 
not too much a burden. But still this is not what it supposed to be.
My drive is a Hitachi travelstar 7200rpm, 60GB.
