Download, copy to your Leopard partition's root directory, then reboot. At the bootloader prompt, type voodoo_beta1 -v to boot into the kernel (with verbose boot messages).

Kernel Features (those with asterisk* need further testing):

Supports sleep/resume as well as SpeedStep on most systems (use in conjunction with the SpeedStep kext)
Massively improved SSE3 Emulation layer, up to 3 times faster and fully multithread-capable (thanks Turbo)
Real-time clock fix for SSE2 users (no system slowdown/stutter when speedstep is on, supports less than 1 GHz cpu speeds)
*Raw ethernet packet support, useful for MAC spoofing and other kinds of network diagnostics (patch by Peter Bartoli)
*More secure: Execute-Disable (XD/NX) is turned on by default for supported systems
HPET enabled on supported systems, cleaner boot-up code
Legacy Vmware support by using busratio= bootflag.

Edit: Tested it just here, and i'm having a instant reboot. So be sure to not install it as default before testing.


Edit2: There is a new build version, this one does work on my system, but i'm getting some audio lag. Trial and error on you're system, DON'T install as default kernel before testing!
