I am also using a self-built kernel 2.6.12.2, and also patched the two files 
by hand. Then I was able to build the kernel module as described on flavio's 
page. I simply followed the instructions on his page, I did not download 
anything from the ATI page. I am also using Debian Sarge.

On my machine things won't work if I use the Kernel's AGPGART-driver, so my 
XF86Config-4 looks like this:

Section "Device"
        Identifier      "ATI Technologies, Inc. Radeon R250 Lf [Radeon 
Mobility
9000 M9]"
#       Driver          "ati"
        Driver          "fglrx"
        Option          "NoTV"                  "yes"
        Option          "VideoOverlay"          "on"
        Option          "OpenGLOverly"          "off"
        Option          "UseInternalAGPGART"    "yes"
        Option          "NoDCC"
EndSection

With that settings everything is working fine here (Debian Sarge, Kernel 
2.6.12.2, IBM Thinkpad T40p with a Radeon Mobility 9000.

On flavios page it says that you should disable CONFIG_FB, so I did that. Did 
you give that a try? Do you really need a splashscreen while booting?
