I'm curious about this change:

-	g_sSysBase.ex_GDT[0x40 << 3].desc_lmh &= 0x8f;
+	g_sSysBase.ex_GDT[0x40 >> 3].desc_lmh &= 0x8f;

I seem to recall yourself or Jake mentioning an issue with the GDT
descriptor, I assume this is the fix?  What effect does this have
E.g. does it fix stability on SMP systems?

I'm guessing that code hasn't changed since AtheOS..how did it ever
work correctly in the first place?
