Netkas has recently released a new version of his PC EFI (V10.4)

It has the following new abilities:

• GraphicsEnabler now supports Radeon hd 2/3 series too, but only for Leopard
• GraphicsEnabler now sets up bin_image property for all radeon hd cards found in system, should fix 100% fan speed issue
• You can tell GraphicsEnabler(GE) to use custom version of bios(for overcloking/changing fan speed/ etc). Use option -useatirom, and GE will look for bios files in /Extra folder (from root and boot partitions, Extra from root partition has more priority). Place bios files to Extra folder and rename them to this format – ati_XXXX_YYYY.rom, where XXXX – devid, and YYYY – vendor-id, for example rom file for 4850 should be named – ati_9442_1002.rom.
• 3rd party sm_cpu_type patch added (well, doesnt work for me anyway) and 3d party patch to
• fix hibernation.
• Proper enumerating of all pci ethernet/video devices
• Fixed few typos
• Support for radeon hd 4730 (rv770 based card) added to GE, the card wasn’t tested tho
• Support for multiple Radeon hd 48×0 cards in SnowLeopard

I try it, but after reboot, my system wont start again. only I see, is BIOS boot promt message screen and then, system still rebooting again, again.... so I must move original file "boot" to root folder.
Have laptop dell d630 and OS retail snow leo 10.6.1 and chameleon bootloader RC3

PC EFI 10.5 now works perfect ;-)
