Yet another sata problem - sda disapeared [SOLVED]

Hi.

I have a problem i find very strange, but it should be something stupid like always.

I re-install Gentoo on a SATA disk. During the install process (even after chrooting), that drive is called /dev/sda/. Grub installed nicely.
I also have an IDE disk.
When I reboot, it looks like it's going to work: i get the usual grub screen, with the splashimage, the kernel boots.

But when it comes to checking the partitions listed in /etc/fstab there is a problem: /dev/sda8 (my / ) isn't a valid ext3 filesystem...

I can enter my root password and try to fix that, but when i list /dev there is no sda nor hda, b or c anymore, and no psaux,... fdisk -l doesn't give anything either.
I found that my hard discs were seen as /dev/discs/disc0 and 1, with the partitions listed as part1,2,3,... there.

I know that i have the right modules compiled into my kernel (not as modules) because i kept my old .config and did "make oldconfig" when recompiling my kernel. I checked manually that the VIA Sata module was marked with a *.

Here is my grub.conf:

laurentgedm,

Do you have hotplug support in the kernel ?

I think so, i have
Device drivers --> Generic Driver Options --> hotplug firmware loading support <*>

EDIT: i don't have "support for PCI Hotplug (Experimental)" in
Bus Optins --> PCI Hotplug Support

Well, hotplug and coldplug were not.
I must have missed something during the installation...

I've emerged them now... but i still get the same problem.

emerge coldplug and hotplug are in the "genkernel users" section... that's why i didn't emerge them.

I forgot to say that i'm doing a stage 3 installation, and that i also kept my "old" rc.conf and make.conf.
I modified my old fstab because i changed my partition scheme.

If you do all of the above and still cannot boot, you might also need to add:

Change grub.conf to refer to the /dev/discs/discX/partY

Then you'll get an error and you'll want to enter in the root password.

Now enter " mount -o rw,remount /"
Now do "nano -w /etc/fstab" and change the /dev entries as neccessary (make them similar to the grub.conf entry I mentioned).

Enter "exit" and it should finish booting.

Ok, i tried that but i then got the error
