Hi,
After trying diferent ways to make the update possible I give you the steps to make it happen simply.

TAKING THE OS TO 10.4.9
--------------------------------

1) Run Software Update and install all but Mac OS X Update (Intel) 10.4.9

2) Download kernel, go to irc channel #1049 at irc.osx86.hu
Read topic, choose sse3 or sse2 kernel, depends on your cpu

5) Go to the terminal and log as root
sudo -s (then enter your password)

6) Backup your Extensions folder
cp -r /System/Library/Extensions /1048

7) Backup your current kernel
cp /mach_kernel /mach_kernel_old

8) Install update MacOSXUpd10.4.9Intel.pkg
For INTEL download from http://www.apple.com/support/downloa...dateintel.html
For AMD extract from 1049_AMD_DELTA.zip
DO NOT PRESS RESTART BUTTON AFTER IT!!!

9) Replace kernel with one downloaded before
cp /where you unpack/mach_kernel /mach_kernel

10) Recover AppleSMBios.kext from the one backuped before
cp -r /1048/AppleSMBios.kext /System/Library/Extensions/

11) Delete AppleIntelCPUPowerManagment.kext if it found
rm -rf /System/Library/Extensions/AppleIntelCPUPowerManagment.kext

12) ONLY FOR AMD Users...
Recover AppleACPIPlatform.kext from the one backuped before
cp -r /1048/AppleACPIPlatform.kext /System/Library/Extensions/

13) Repair kexts permissions
chmod -R 755 /System/Library/Extensions
chown -R root:wheel /System/Library/Extensions

14) Delete Extensions.kextcache and Extensions.mkext
rm -rf /System/Library/Extensions.kextcache /System/Library/Extensions.mkext

15) To avoid diskarb errors make the following
rm /etc/rc.installer_cleanup

16) Reboot

17) To test the update use: uname -a

Notes:
A) If you have problems with loginwindow, apply this patch 10.4.4.loginwindow.pkg
B) If you have problems sharing files, apply this patch MPIP103_10.4.9.SMB.CIFS.APF.FIX.dmg


APPLYING SECURITY UPDATE 2007-005
------------------------------------------------

1) Download the patched versions of some files and unzip into /patch
http://www.mediafire.com/?fqlhrdydcso

2) Run Software Update and install all the updates

3) Boot in single mode
At the system start use -s

4) Mount the file system with read/write rights
/sbin/mount -uw /

5) sh /patch/patch.txt


That's all.. after all of these step you have an updated system!
