Here is a picture of the screen as it appears a few seconds after selecting "* Gentoo GNU / Linux" in Grub 2.0 :

Although I have followed as closely as possible the *handbook*, I probably made ​​a mistake during the installation process. Could someone point me to where this error?

Thanks in advance

Could it be related with the kernel not being able to find or mount the /root partition?

You should consider the following:

1.- Do you have the right kernel modules for your hard drive?
2.- Is your hard drive correctly set in grub.cfg?

1.- Booting from a live-usb, you can check what kernel drive is used by:
Code:
lspci
00:1f.2 SATA controller: Intel Corporation 5 Series/3400 Series Chipset 4 port SATA AHCI Controller (rev 06)

lspci -s 00:1f.2 -k                                                                                                     11:29 3001┘
00:1f.2 SATA controller: Intel Corporation 5 Series/3400 Series Chipset 4 port SATA AHCI Controller (rev 06)
   Subsystem: Toshiba America Info Systems Device 0001
   Kernel driver in use: ahci


2.- You could use a simple grub.cfg, like:

Code:
default=0
timeout=5

menuentry 'Gentoo' {
   root=hd0,1
   linux /boot/gentoo root=/dev/sda3
}


Or use auto-completion in GRUB CLI Mode to see what drives can GRUB identify.

Cheers!

Check for:
1. Do you have appropriate driver for your sata controller built in kernel?
2. Do you have DEVTMPFS / DEVTMPFS_MOUNT enabled?
3. Correct root device (/dev/sdX) passed to kernel command line by Grub
Most likely you problem arises due to first two. The should be built-in <y>, not built as modules <m>.
Boot liveCD, chroot into installed system and run "lspci -k" command. It wills show which kernel module requires for your sata controller.
Run "make menuconfug", press "/" key and type module name and press Enter. It will show do you have module built-in, built as module or missed at all.
Check for DEVTMPFS as well.

Thank you both! I had not compiled "sata_via". Now I get to start. :)
