DSDT patch in kernel for Compaq 8510p

On OpenSUSE 11.2 M8 i have to patch the kernel....these steps i've taken:

iasl -tc DSTL.dls generates a DSTL.hex


make oldconfig
cp .config .config_old
make clean
make mrproper
make menuconfig


with menuconfig i've patched the kernel to use /etc/acpi/DSTL.hex

CONFIG_ACPI_CUSTOM_DSDT_FILE="/etc/acpi/DSDT.hex"
CONFIG_ACPI_CUSTOM_DSDT=y

see http://www.lesswatts.org/projects/acpi/overridingDSDT.php

make -j3
make modules
make modules_install

make bzImage

cp arch/i386/boot/bzImage /boot/vmlinuz-2.6.31-10-desktop
cp System.map /boot/System.map-2.6.31-10-desktop
vi /boot/grub/menu.lst
and adding the proper entry copying from the others
mkinitrd -i /boot/initrd-2.6.31-10-desktop -k /boot/vmlinuz-2.6.31-10-desktop

result:

[    0.000000] ACPI: Override [DSDT-   8510x], this is unsafe: tainting kernel
[    0.000000] ACPI: DSDT @ 0x000000007ffc84c0 Table override, replaced with:
