This is not auto-detected with the default SuSE 10.2 kernel (22.214.171.124), but unlike SuSE 10.1, the advansys module has been compiled and is available.
You can `modprobe advansys' after boot-time. Alternatively, start `YaST2 -- System -- /etc/sysconfig editor'. Go to `System -- Kernel'. Add advansys either to INITRD_MODULES or MODULES_LOADED_ON_BOOT. If you decide to add advansys to INITRD_MODULES then you need to run `mkinitrd' as root to change the /boot/initrd-xxx files.
