Com relação ao meu post "kernel panic", depois de muito procurar achei a solução
no forum Kernel & Hardware no post do NeddySeagoon:

NeddySeagoons' Rough Guide to Intel ICH7 Chip Set
Edit - Now tested with ICH4, ICH5, ICH6, ICH7, and ICH8 too

Regardless of the electrical connection of the drives to the motherboard, you will use the SCSI high level later.
All your drives will appear as SCSI devices. This means you will have to change grub.conf and /etc/fstab if you have PATA drives.

You have an Intel ICH7 Family chip set. genkernel will net set this one up correctly, so you have to help it if you want to use genkernel.
In make menuconfig choose the following options:-
Device Drivers --->
< > ATA/ATAPI/MFM/RLL support --->
turn off the ATA/ATAPI/MFM/RLL support menu item entirely.
You may think this will prevent your CDROM working - it won't. I'll explain later.
<*> Serial ATA (prod) and Parallel ATA (experimental) drivers --->
<*> Intel ESB, ICH, PIIX3, PIIX4 PATA/SATA support
notice how it says PATA/SATA in the name. This driver is a combined driver for both SATA and IDE modes - its peculiar to Intel. All other options on this menu must be off, including the two Intel PATA options close to the bottom. If you get that wrong your hard drive will appear as an IDE drive and be very slow as you will not get DMA modes.
Thats the low level drivers set.
Now the high level driver
go back up to
SCSI device support --->
Inside that menu choose
│ │ < > RAID Transport Class
│ │ -*- SCSI device support
│ │ < > SCSI target support
│ │ [*] legacy /proc/scsi/ support
│ │ *** SCSI support type (disk, tape, CD-ROM) ***
│ │ <*> SCSI disk support
│ │ < > SCSI tape support
│ │ < > SCSI OnStream SC-x0 tape support
│ │ <*> SCSI CDROM support
SCSI CDROM support may be either <M> or <*> but your CDROM is going to be treated as a SCSI device now. It will have two entries in /dev, /dev/sr0 which is the block device you use in the normal way and /dev/sg0 which is its controlling charater device. Normally, you don't need to know that as udev takes care of creating the symlinks properly. However, if your CDROm is listed in /etc/fstab as /dev/hd... that will need to change.

Edit - with thanks to ilm
Note - ICH8 and ICH9 chipsets have been seen with AHCI SATA hardware, in which case you will need
<*> AHCI SATA support
<*> Intel ESB, ICH, PIIX3, PIIX4 PATA/SATA support

If you are sure you only have AHCI hardware, Intel ESB, ICH, PIIX3, PIIX4 PATA/SATA support is not required.

Edit - with apologies to Mort_pp
Note, Some ICH9 chipsets have a supporting Jmicron PATA/SATA chip. If this is listed in your lspci, you will need
<*> JMicron PATA support
