Tomo,
I patched your driver into the 2.6.27-rc1 kernel. After compiling the driver I get:

[root@testmonkey linux-2.6]# insmod drivers/scsi/ciss.ko
insmod: error inserting 'drivers/scsi/ciss.ko': -1 Invalid module format

[root@testmonkey linux-2.6]# gcc --version
gcc (GCC) 4.1.2 20071124 (Red Hat 4.1.2-42)

[root@testmonkey linux-2.6]# uname -r
2.6.26

I built inside the tree. Any thoughts?
