Yes, it is a module problem. You have to find out which modules are needed
for your card.
From DVD:
and the dependencies of the module:
Then you have to create a ramdisk with the scsi modules inside.
Here is a good ramdisk tutorial using initramfs:
http://en.gentoo-wiki.com/wiki/Initramfs
Copy the necessary modules from /lib/modules/2.6.28-gentoo-r2/kernel/drivers/scsi/... to the initramfs directory.
There is a line in the init script:
# do your magic here
There you have to insert:
insmod /PATH_TO/MODULE_NAME1
insmod /PATH_TO/MODULE_NAME2
insmod /PATH_TO/MODULE_NAME3
...
Copy the finished minirt.gz to /boot of your mounted Toorox partition and edit /mnt/toorox-partition/boot/grub/grub.conf:
Remove # in the initrd line.
Finish! Toorox should boot now.
