Hard to get this out of Via, they don't do datasheets for ordinary 
folks, but posts on the newsgroups seem to indicate p6 compatibility in 
some versions anyway:

 From a post in linux.kernel:
cat /proc/cpuinfo:

fdiv_bug        : no
hlt_bug         : no
f00f_bug        : no
coma_bug        : no
fpu             : yes
fpu_exception   : yes

flags           : fpu de tsc msr cx8 mtrr pge mmx 3dnow

I'll try the XIP_ROM_SIZE etc tomorrow.
