for the apple power management issue you can add nullcpu kext or delete the kext from s/l/e or generate an SSDT for for your ivy powermanegment using the option of plugin type=1 if you make any kext changes or deletions you need to run a my fix quick option so it generates new kernel cache.
for the fakesmc issue update fakesmc. without that kext osx will not work.
for HP lapic issues you need to patch the kernel. i don't think chameleon wizard does that.
clover boot loader might have an APIC fix option in ACPI section but thats a totally different animal then chameleon.
