You got several possible drivers to drive the DC390F:
1) ncr53c8xx
2) 53c7,8xx
3) tmscsiw

I'd recommend the first one and enable the NVRam detection. It works
perfectly here.
I didn't test the 53c7,8xx.
The tmscsiw driver is adapter specific and can be found on
(filename is something like dc390wuf.diff). This one works as well.

Don't forget to compile it into the kernel, to insmod it in your bootup
scripts or to tell your kerneld to load it, when accessing block-major-8.
