patch RTAI (fusion-0.6.4) with kernel 2.6.9 on Fedora Core 3

["Yihan Li" <Yihan.Li@Edgewater.CA>]

Need help again!
I am trying to patch RTAI (fusion-0.6.4) with kernel 2.6.9 on Fedora Core 3.
The following steps are what I was following:

I download a varnilla version of linux-2.6.9 from www.kernel.org,
Unpack the kernel source:
# cd /usr/src
# tar xvjf linux-2.6.9.tar.bz2
# ln -s linux-2.6.9 linux

Unpack or copy RTAI to  /usr/src/fusion-0.6.4.tar.bz2
# ln -s fusion-0.6.4  rtai

Patch the kernel:
I download patch 2.6.9-ac15 and patch to kernel 2.6.9
Then I patched RTAI to kernel:
# cd /usr/src/linux
# patch -p1 < ../rtai/arch/i386/patches/adeos-linux-2.6.9-i386-r8.patch

Copy the existing (Fedora) kernel config file to /usr/src/linux
# cp /boot/config-2.6.xxxx /usr/src/linux/.configConfigure the kernel:
# make menuconfig
# make

After 8 mins, I get error messages as following:
drivers/scsi/qla2xxx/qla_os.c: In function `qla2x00_queuecommand':
drivers/scsi/qla2xxx/qla_os.c:315: sorry, unimplemented: inlining failed in

I looked at the source code of qla_os.c, which belong to Qlogic ISP2x00 
device driver.
So I redo my configuration. I didn't choose Qlogic ISP2x00 and Qlogic PCMCIA 
device driver.
After that, the make finished without error.
Then I install the kernel:
# make modules_install install

The following warning is what I got:

  INSTALL sound/usb/snd-usb-lib.ko

Module sata_via is mainly for what? What can I do now? I need a hand ...

I wish to be personally CC'ed the answers/comments in response to my
posting.
