I know that Toh team are more involved in PC_EFI thing but I am very curious. Did you plan to take any effort to make speedstep on SSE2 working? By this, you will make SSE2 users dream come true.

I check this blog regularly. You never mention that speedstep works on SSE2, last post about SSE2 has

Quote
Also u can find sse3/sse2(unversal) kernel which should be able to sleep(even on sse2) if ur hardware sllows to sleep with osx. this kernel can’t make speedstep

I check 10.5 channel and there are kernels as follow

9.1.0 speedstep/intel/amd/sse3 kernel
9.0.0/speedstep sse3 kernel
sse2 10.5.1/10.5 kernel
9.1.0/9.0.0 sleep sse3/sse2 kernel

With one has speedstep. I am talking about SSE2 not SSE3 kernel

Unfortunately I can't test this kernel, ToH RC2 reboot when booting, Must wait for iatkos.

Can someone confirm that speedstep on SSE2 works without "slowdown" on Leopard
