But that was most likely already enabled in several kernels that I have 
tried before. The first thing I tried, actually, was to install a kernel 
derived from the LiveCD's kernel configuration.
Anyway, it might have been the case that I did something wrong in the 
beginning which resulted in the LiveCD kernel config never being used.
In that case you're right!

It was partitioned using fdisk.

For any of you who has this problem in the future:

Try using the kernel configuration from the LiveCD. I did zcat 
/proc/config.gz > /etc/kernel/kernel-config-x86-2.6.19-r5 (be sure to 
name the configuration according to your kernel version). Run `genkernel 
--menuconfig all` and be sure that the LSI drivers (Device Drivers > 
SCSI device support > SCSI low-level drivers) are all compiled into 
kernel. And also that EFI GUID Partition support is enabled (File 
systems > Partition types).

I will report back if I notice anything more.

Thank you all for your help!
/P.
