MacOS X (Leopard) on Dell Inspiron 1300 installation

Hardware: Dell Inspiron 1300
Software: iDeneb (hackintosh) v1.3 10.5.5 MacOSX Leopard.

The main problems seemed to be the built-in video card (Intel GMA915) and soundcard (SigmaTel).
Some digging gave following workaround (steps to reproduce):

1. Install iDeneb

2. Reboot and use -s option to remain in console and issue commands:
# mount -uw /
# touch /var/db/.AppleSetupDone
# cd /System/Library/Extensions/
# mv AppleIntelGMA950.kext /var/
# mv AppleIntelIntelintegratedFramebuffer.kext /var/some-bkup-place/
# reboot

3. Get AppleIntelIntelintegratedFramebuffer.kext and ElliotappleIntelGMA950LegacyEnabler.kext from InsanelyMAC.com

4. Upon reboot launch terminal (under root) and run commands:
# cp -R ElliotappleIntelGMA950LegacyEnabler.kext /System/Library/Extensions/
# cp -R AppleIntelIntelintegratedFramebuffer.kext /System/Library/Extensions/
# mv /var/AppleIntelGMA950.kext
##note: restore for old backuped AppleIntelIntelintegratedFramebuffer.kext is NOT needed
# rm Extensions.kextcache Extensions.mkext
# reboot

5. Now graphics should work!

6. As for the sound, this page helps: Taruga's patch on InsanelyMac.
