Updating a driver quirk in kernel


Os : Debian 6 Kernel Version : 2.6.32

I have been recently working with Linux application and now we have some little hard-disk issues where my motherboard doesn't support AHCI through bios. On various Google searches i found that i can force Linux kernel force load driver to AHCI mode.

i have just now started my kernel walk through and i am very new for handling issues.

THS IS THE QUIRK WHICH I FOUND WILL WORK : http://tartarus.org/~ds/quirk-ich-force-ahci.patch

I download the kernel and its respective headers and did a complete kernel build.since its Debian updated it in the client machine and found it was working as expected

linux-image-2.6.32_2.6.32-2_i386.deb -- 26MB
linux-firmware-image_2.6.32-2_all.deb -- 5k
but now i need to apply the patch in all my client machines which i located n remote locations where 26 mb in the network is very high

Is there a way where only this quirk can be updated in client in a reduce size like some KO file update.

Is this the only way way to update the driver?? need some guidelines on the same.

i also saw : http://www.cyberciti.biz/faq/add-rem...ernel-modules/

in my case can someone guide me with some pointers how this has to be done

Please guide

The patch updates the file /drivers/pci/quirks.c, which is a part of the kernel core and cannot be compiled or loaded as a module. Short of using ksplice, I don't know of any way to distribute this patch other than replacing the entire kernel.

2.6.32 is pretty ancient, released in December 2009. Have you considered checking more recent kernels to see if the quirk (or perhaps an improved version of it) has been incorporated into mainline?
