Everything working here for me. I can use Logic 9 64 bit with 32 bit plugins, like on my macbook!!! I'm booting mac os with:
arch=i386 -force64 -maxmem=4096 busratio=20

I'm using andy kernel v4 and AMD sysenter trap patch (10.6.4)(I patched sysenter_patch with maxxuss patcher gui)

ANDY THANK YOU VERY MUCH FOR ALL YOUR HARD WORK!!!

I have Amd Phenom x4 965 Processor
