The supported hardware list: http://www.ihackintosh.com/2009/02/ipc-osx86-1056-final-ppf5-complete-driver-list/

Intallation options:
========
try not to select extra driver and patches, which can be installed easily after successful installation.

To remove kext cache in 10.5.6 or later just run:
sudo rm -rf /System/Library/Extensions.mkext

Kernel: 9.5 voodoo (the default kernel 9.6 will bring black screen; After upgrade to 10.5.7, the voodoo kernel need to be reinstalled)
ethernet driver: intel pro/100 ve (tips for your particular device: modifying Info.plist)
audio: the patch or driver coming with this iso doesn't work for my Dell Dimension 5150, the available driver is here.
video: typing '-x "Graphics Mode"="1280x1024x32@85" as boot flag to change the screen resolution. More details are here.
Alternatively, using ATI 9700 driver as the driver for x300, this will remove small square around mouse, but still no QE support in Leopard. + ATI Radeon x300 PCI-Ex Callisto v.008 to change the screen resolution.

patch:
seatbelt (to solve mounting dmg file kernel panic issue)
shutdown (seems not work properly)
"NTFS-3g (http://www.ntfs-3g.org/)" can be installed later as a software

Sleep problem: (I did both together, so far don't know which fixed this problem. This happened when I upgrade to 10.5.7)
1) try to remove useless ATI and Gefore kext from /System/Library/Extensions.
2) GMA driver ( I removed the ATI VGA card, because it doesn't support Quartz Extreme. )
