I20 disk driver, etc.. Should I use?

I have the Adaptec AIC-7902 controller. This is a bigger number than the
controller listed in the first line of the i2o compatibles. Is this OK?

-----

Looks like I don't currently have i2o installed

[root at hoho2 user1]# /sbin/lsmod | grep i2o
zit, nada

However, I do have the i2o_proc.ko module hanging around in what looks like
a good spot (smp 607)

[root at hoho2 user1]# find / -name i2o_proc.ko -print
/lib/modules/2.6.8-1.603/kernel/drivers/message/i2o/i2o_proc.ko
/lib/modules/2.6.8-1.607smp/kernel/drivers/message/i2o/i2o_proc.ko
/lib/modules/2.6.8-1.607/kernel/drivers/message/i2o/i2o_proc.ko
/lib/modules/2.6.8-1.603smp/kernel/drivers/message/i2o/i2o_proc.ko

What is the easiest (and safest) way to proceed from this starting point,
without having to go back to anacondo (the big bang stage).

Can I just do:

/sbin/insmod i2o_proc.ko
/sbin/lsmod | grep i2o

and then reboot?

Or stick something into /etc/modprobe.conf ??
