>Description:
-current kernel cannot detect IDT's WinChips correctly.
>How-To-Repeat:
Replace your Pentium with a WinChip and boot FreeBSD.
>Fix:
According to data sheet, WinChips (C6 and 2) are almost
compatible with Pentium and have no special features on our
use. So all we have to do is to print the name and features
correctly. Following patch is tested on WinChip C6.
