Hard drives only detected when booting from CD on nVidia MCP67 SATA

With kernel 2.6.23 on an Acer 7220 notebook using nVidia MCP67 SATA, hard drives are only detected after first booting from a CD.

Boot from hard drive No drives detected

Boot live CD Detected

Boot CD to GRUB menu, Detected
then warm-boot from hard
drive

Non-detect case:

But, if a LiveCD is used to boot or if a LiveCD was used before an hot reboot (without a power off), disks are correctly found :
