Hi there,

It says:
mtrr: detected mtrr type: none

So I guess that's that...

Ok, I did exactly that and I get:
BENCHMARKs: V:  140.827s VO: 0.000s  A: 0.000s Sys: 62.919s = 203.746s
BENCHMARK%: V: 69.1190% VO: 0.000% A: 0.0000% Sys: 30.8810% = 100.0000%

So, what does that tell about the 400MHz Crusoe? The picture quality itself 
looks really good, just a bit slow. I'll be damned if that sluggishness 
comes just because of missing mtrr...:(
