I saw the more recent postings...

My understanding is that the TX4650 has the RAID-5 XOR ASICs to 
accelerate the reed-solomon code calculations... hence my wanting to use 
this driver.

I picked up the patches that you pointed me at (including "The Czar's", 
which was necessary to compile on 2.6.25 and subsequent)...

Then I looked at:

http://fedoraproject.org/wiki/Docs/CustomKernel?highlight=#Building_Only_Kernel_Modules


but had some questions about that.

The example is a little thin.  It doesn't explain what to do if you need 
to pass in extra C flags, extra include directories, or if your driver 
has several subdirectories that need to be compiled and linked together 
(or if it is a partial-source release, and has canned object files that 
also need to be linked in).

Anyone have a real-life example that they can point me at that does this?

Thanks,
