Now that I'm more awake than last night ;), I can't say whether or not
this is correct. I won't touch Centaurs. However, it's possible, maybe
probable. If anyone would like to volunteer to check for us, it'd be
greatly appreciated. :)
if ((boot_cpu_data.x86_capability & 16) && (boot_cpu_data.x86_vendor !=
X86_VENDOR_CYRIX) && (boot_cpu_data.x86_vendor == X86_VENDOR_CENTAUR
(boot_cpu_data.x86_stepping == 0))) {
That may or may not be correct, probably not. I'm still not entirely
awake, and I threw that together in my head in a second or two. However,
you get the gist of the idea, right? :)
For those of you who don't...
If x86_capability & 16 and VENDOR != Cyrix and VENDOR == Centaur and
STEPPING == 0...
yaddayadda. :) Why risk breaking CPUs that aren't already 'broken?' ;)
