These VIA C3 processors are basically a low-power Pentium+MMX processor, and 
I've used:

CPUTYPE=pentium
CFLAGS=-O2 -pipe

...OK under later 5.x and 6.x releases.  Using CPUTYPE=i686/pentium2 resulted 
in the bootloader and the kernel containing instructions which the CPU 
couldn't handle (ie, the system halted and panic'ed) when I tried.

I believe you could use CPUTYPE=pentiumpro or pentium-mmx OK, but there didn't 
seem to be any performance difference, and I'm leery of chasing the compiler 
optimizer too far when it doesn't change the system performance by a noticable 
amount.
