We've worked hard on making a non-double faulting bootloader (the credits go to cparm for this).
I've constructed a PC EFI 10.6 that will work on both Lion and older.
It is no longer required to use the kernelcache (you can use also Extensions.mkext or just .kext files)
This is only the first step in the line, next will be an AnVAL and I'm sure cparm will release stuff too
I've also attached atom / new Celeron patched kernel but it'll only work for 64bit cpu's (apple is dropping their legacy 32bit support since Lion with every step...).
Even with DP1 and perfect bootloader and patched kernel it'll halt execution after launchd is launched so...
Patch for Snow Leopard PC EFI 10.6 is also included...
Update: I patched the kernels for Atom (DP1 32+64bit cpus work, DP2 to DP4 64bit cpus work) and also added a little APIC fix (needed for some computers like the HP Mini...).
Atom APIC fixed Kernels for DP1 to DP4:
