with both patches applied it causes

$ ./checkasm.exe
x264: using random seed 2618250584
x264: All tests passed Yeah :)

and

x264 [error]: your cpu does not support MMXEXT, but x264 was compiled
with asm support
x264 [error]: to run x264, recompile without asm support (configure
--disable-asm)
x264 [error]: x264_encoder_open failed

while as BugMaster's patch by itself works fine.
so Loren's patch is apparently breaking x264_cpu_cpuid
