[PATCH] i386: fall back to sensible CPU model name

When vendor-specific i386 initialization code is unavailable the kernel
falls back to a default CPU model name.  Make that model name reflect the
CPU family instead of an internal vendor index.

Tested on Pentium II (family 6 model 5).

/proc/cpuinfo before:
        model name     : ff/05

after:
        model name     : 06/05
