`#if defined(ONE_THING)' is a style bug, and i386 instead of __i386__ is a bug, since i386 is never defined when the kernel is compiled by with the default flags (`gcc -ansi ...'). Here the bug disabled the call to pmap_setvidram(), so ISA video memory was not mapped WC on 686's. The bug may have been masked by bugs in the committer's version of gcc - `gcc -ansi' incorrectly defines i386 for gcc = the version of egcs on the 2.2.6 cdrom.
