I'm now quoting mkp:

But the other reason the cpqfcTS driver is special is the RA4100
array.  The two were sold as a packaged solution.  The RA4100 isn't a
"real" fibre channel disk device.  It represents itself as a TYPE_RAID
as opposed to TYPE_DISK.  So even if you had my driver in 2.6.5, you
wouldn't be able to use it.

What he was talking about as his driver is a replacement he writes for cpqfc. 
cpqfc was deleted from 2.6 because it was horribly written and currently 
broken. The 2.4 version is the same, but it might work because the 2.4 
infrastructure is different from the 2.6 one.
