Indeed yes, I managed to compile the megaraid_sas module by using an older
version of it (looks like the latest source code from LSI has an issue with
Debian). I see you follow very well what happens on this mailing list :)
Thanks for your suggestion of the USB key, unfortunately that's exactly what I
would like to avoid as I want to setup a fully automated installation using
Debian's preseed so going to the server and add a USB key is not really an
option. Can't I somehow modify the PXE netinstall initrd.gz image to add there
directly my self-compiled version of the kernel module?
Cheers,
ML

So you finally managed to compile the driver for Debian, congrats! :-)

A dirty trick can be placing/copying the kernel module under "/lib/
modules/$(uname -r)/kernel/drivers/scsi" from the installer itself.
You will need to put file into a USB stick and jump to a console to
manually mount the USB disk ("mount /dev/sdb1" /mnt) and then issue a
simple "cp /dev/sdb1/megaraid_sas.ko /lib/modules/$(uname -r)/kernel/
drivers/scsi/" (note that YMMV with names and paths, do not copy/paste
"as is"). After that I supoose you will have to "modprobe megaraid_sas"
so the module becomes available from the partitioner.
P.S. Remember that the kernel module you have self-compiled has to match
with the kernel version you are going to use, otherwise it will fail to
load ;-(
